I think A sounds the best here. The answer choices all seem a bit awkward.

A. sequence of tense.

Galileo did not invent the telescope, but on hearing, in 1609, that such an optical instrument had been made, he quickly built his own device from an organ pipe and spectacle lenses.

1. "Galileo did not invent the telescope" is an independent clause.
2. "but on hearing, in 1609, that such an optical instrument had been made" is a dependent clause.
3. "he quickly built his own device from an organ pipe and spectacle lenses" is an independent clause.

Sequense of events: "such an optical instrument had been made" occured before "Galileo did not invent the telescope" and "he quickly built his own device from an organ pipe and spectacle lenses". so

1. "Galileo did not invent the telescope" is in past perfect tense.
2. "but on hearing, in 1609, that such an optical instrument had been made" is in simple past tense.
3. "he quickly built his own device from an organ pipe and spectacle lenses" is in simple past tense.

so choices other than A violets these rules and are incorrect....

I would go with A.

A: Correct
B: wrong use of verb tenses -- had not invented implies that he will invent the telescope in the future
C: Galileo, on hearing that such an optical instrument had been made, he -- totally wrong
D: missing "he" at the end
E: "even though" and "but" are redundant

B, D -- are out.. "he" is missing before "quicklly"
C -- Galileo,...,he .. he is redundant
E. eventhough .. but --> redundant and "being made" --> wrong

A -- looks better.

Galileo didn't invednted (pastense),... optical instrument had been made.(past perfect -- passive voice.)

pefect..

To be frank i found it tough

Did not invent should be correct since invention is one time event
had not invnted deviates us thinkin he had not invented but can invent later .So eliminate B,C
NOw remains A,D,E :
E is eliminated since even though... but usage is not suggested
D is eliminated since HE is missing here statement apopears incomplete
A is perfect => IMO A

Correct useage of tenses, right placement of but.
In GMAT, not always but most of the times, you can eliminate choices with 'having' & 'being'.
