IMO,

It's a question on parallelism. ' That' has to be repeated in the second part of the sentence( that is.........'and that' is.....).

A, B are out. E changes the meaning and usage of 'it' is ambiguous. D is awkard and is also in the past tense

I'll go with C

Cheers,
unplugged

But in C, isnt the use of 'that' and 'it' redundant? both are referring to asteroid!

"it were to strike earth" is a modifier clause to "that". Hence, the use of "it" is ok.

Scientists have identified an asteroid, 2000 BF19, that is about half a mile wide and that,< if it were to strike Earth>, could do tremendous damage to part of the planet but would probably not cause planetwide destruction

remove the sentence between commas and read.. then C makes sense.

that is about half a mile wide and that could do tremendous..

that is necessary to maintain parallelism and correct usage.

if it were to strike Earth , that would probably not cause planet wide destruction --> correctly describes the hypothetical situtation.

"if it were to strike Earth" --> i don't see the best way to rewrite this statement without using "it". If you can try it

and, if it strikes Earth, it can do tremendous damage to part of the planet but

I agree that in E .. "it" after comma is redundant.

A. and, if it strikes Earth, it can do tremendous damage to part of the planet but -- it can refer back to earh or asteroid.. not clear..Hence, incorrect.

B. and, if it would strike Earth, part of the planet could experience a tremendous amount of damage but it would -- it can refer to part of the planet, asteroid or earth.. not clear..Hence, incorrect.

C. and that, if it were to strike Earth, could do tremendous damage to part of the planet but would -- correct..subjunctive mood for hypothetical situations..

D. and that, if earth struck by it can do part of the planet tremendous damage, but it would -- Passive..seems like earth is causing the damage.Hence, incorrect.

E. and that, if it strikes earth, it could experience a tremendous amount of damage but --Who will exprience damage ? earth or asteroid..not clear...hence, incorrect.

C has a problem: It is missing the word "it" before "could". Try reading it with skipping the middle clause: "... and that could do tremendous damage". Please explain.

guys what is wrong with A as it refers to singular, shouldn't we use strikes instead of strike.

@viren what is the OA ?

I think C is correct. If you add the word "it" to the sentence, it would no longer be structurally parallel:

Scientist have identified an asteroid, 2000 BF19, that is... and that it could do... (Is NOT parallel: THAT + VERB / THAT + PRONOUN + VERB).

So it would be better to go with answer C:
Scientist have identified an asteroid, 2000 BF19, that is... and that could do... (Is parallel: THAT + VERB / THAT + VERB).

a great take away point that x2suresh mentioned is to remove commas from the sentence and see which option makes the sentence more appealing.

@ ritula and x2Suresh

IMO

E changes the meaning - Its the asteroid that may cause damage on earth. The possessive it used before earth and after earth in E is ambiguous and doesn't have a clear noun reference (Earth or Asteroid).

Where as C is not only parallel, but also uses subjunctive form (if it were...X...It Would..Y) to signify - the probability of it not causing planet wise destruction.

A. and, if it strikes Earth, it can do tremendous damage to part of the planet but
B. and, if it would strike Earth, part of the planet could experience a tremendous amount of damage but it would
C. and that, if it were to strike Earth, could do tremendous damage to part of the planet but would
D. and that, if Earth is struck by it, can do part of the planet tremendous damage, but it would
E. and that, if it strikes Earth, it could experience a tremendous amount of damage but

This a conditional sentence Such as I wish I were a bird [but i am not a bird], thus it were strike the earth [But did not strike], could and would for conditional sentence.

I think, as far as parallelism is concerned, both "that" should have the same function. But here, first "that" is referring to the asteroid and the second "that" is a relative pronoun that starts a clause.

second THAT is used because of parallelism but this is also refering to ASTEROID.
