In d, putting comma between astronomers and working makes the meaning of the sentence different from b (without comma)

Between "estimate to be" vs. "estimate to have" because this sentence go with measurement, infinitive is prefer. We cannot say that "gas sphere" is "5 to 15 times" that "estimate to be" say. Another usage, "estimate"can go before "that"

Comma make the part between comma become restrictive. In this sentence, we need non-restrictive adjective phrase. If we put the comma, the sentence become that all the astronomer in the world are those who working at telescopes in the Canary Islands and Spain. We need to say that some of astronomer in unique field work at telescope in the Canary Island and Spain.

Choice A is correct one.

+1 for A.

The problem with B is the phrase "...estimated to be 5 to 15 times Jupiter’s mass" .

"Estimated to be...mass" in option B is wrong.
"Mass" is something that one "has". That is why "have" in A is correct.

"The gas spheres have a mass 5 to 15 times that of Jupiter". This sentence makes sense.

Hence, A is the correct answer.

The phrase after the underlined portion " the solar system’s largest planet" should modify a planet. Hence option B & E are ruled out.

An international team of astronomers working at telescopes in the Canary Islands and Spain has detected at least 18 huge gas spheres estimated to have 5 to 15 times the mass of Jupiter, the solar system’s largest planet.

A.) astronomers working at telescopes in the Canary Islands and Spain has detected at least 18 huge gas spheres estimated to have 5 to 15 times the mass of Jupiter
B.) astronomers working at telescopes in the Canary Islands and Spain has detected at least 18 huge gas spheres estimated to be 5 to 15 times Jupiter’s mass - modifier issue
C.) astronomers is working at telescopes in the Canary Islands and Spain, having detected at least 18 huge gas sphere that are estimated at 5 to 15 times the mass of Jupiter - Subject - Verb agreement issue - "astronomers" plural, "is" singular
D.) astronomers, working at telescopes in the Canary Islands and Spain, and has detected at least 18 huge gas spheres estimated at 5 to 15 times the mass of Jupiter -parallelism issue and no complete clause available - "astronomers , xxxxx--modifier--xx, and has detected at least....
E.) astronomers, working at telescopes in the Canary Islands and Spain, has detected at least 18 huge gas spheres they have estimated to be 5 to 15 times Jupiter’s mass - modifier issue

Hence option A is the correct one

The problem with B is that it compares the Gas Spheres to Jupiter's Mass: "spheres estimated to be 5 to 15 times Jupiter's mass". You cannot compare an object such as a Gas Sphere to something abstract such as mass. You can only compare mass with mass.

A correctly compares the mass of the spheres to the mass of Jupiter: "spheres estimated to have 5 to 15 times the mass of Jupiter"

An international team of astronomers working at telescopes in the Canary islands and Spain has detected at least 18 huge gas spheres estimated to have 5 to 15 times the mass of Jupiter, the solar system's largest planet.

Three very easy decision points here
1) Idiom :- estimated at is wrong ; estimated to /to be is correct
2) Subject Verb agreement :- "Team" is singular therefore singular verb should be used.
3) Modifier - "the solar system's largest planet" should modify JUPITER and not Jupiter's mass because Jupiter's mass cannot be a planet.

A. astronomers working at telescopes in the Canary islands and Spain has detected at least 18 huge gas spheres estimated to have 5 to 15 times the mass of Jupiter, the solar system's largest planet.
CORRECT

B. astronomers working at telescopes in the Canary islands and Spain has detected at least 18 huge gas spheres estimated to be 5 to 15 times Jupiter's mass
INCORRECT:- jupiter's mass cannot be the largest planet ; Jupiter is the largest planet.

C. astronomers is working at telescopes in the Canary islands and Spain, having detected at least 18 huge gas spheres that are estimated at 5 to 15 times the mass of Jupiter
WRONG:- having is incorrect tense. Estimated at is wrong idiom

D. astronomers, working at telescopes in the Canary islands and Spain, and has detected at least 18 huge gas spheres estimated at 5 to 15 times the mass of Jupiter
WRONG:- Estimated at is wrong idiom

E. astronomers, working at telescopes in the Canary islands and Spain, has detected at least 18 huge gas spheres they have estimated to be 5 to 15 times Jupiter's mass
INCORRECT:- Team is singular and the subject of the sentence. therefore "they" is wrong pronoun and is used incorrectly "have" is incorrect; Jupiter's mass is incorrect because mass cannot the biggest planet.
