Option(E) is correct
There are two main problems with the original sentence.
(1) the infinitive form to enable needs to be replaced by a phrase that modifies to develop faster. The correct modifying phrase cannot be in the infinitive form and should instead be a participle: enabling
(2) it is not grammatically correct to compare AMD employees (i.e., them) to the firm Intel as you cannot compare unlike parts. Instead, you must compare like parts: a firm (i.e., AMD) to a firm (i.e., Intel).
The correct choice should include to gain substantial market share from and not market share with, which changes the meaning of the sentence.
A. to enable improperly modifies the phrase it follows and should be replaced by the participle form enabling; Illogically compares employees (i.e., them, referring to AMD employees) to a firm (i.e., Intel)
B. the word with instead of from in the phrase to gain substantial market share with rival firm Intel entirely changes the meaning of the sentence and is wrong
C. Illogically compares employees (i.e., them, referring to AMD employees) to a firm (i.e., Intel)
D. to enable improperly modifies the phrase it follows and should be replaced by the participle form enabling
E. correctly used the participle form instead of the infinitive to modify the preceding phrase; compares a firm (i.e., AMD) to a firm (i.e., Intel); correctly uses the phrasemarket share from rival firm
