(A) The convent was the perfect environment for Sor Juana to pursue intellectual pursuits, achieving
(B) Sor Juana found that the convent provided the perfect environment for intellectual pursuits, and she went on to achieve
(C) The convent provided the perfect environment for intellectual pursuits for Sor Juana; going on to achieve
(D) Sor Juana found that the convent provided the perfect environment for intellectual pursuits; achieving

1.The first thing to be noticed is the noun that follows comma after noun modifier clause: "Born in the mid-seventeenth....". The noun should be a person i.e. Sor Juana and not the convent. Hence, (A), (C) and (E) is out

2. Considering (B) and (D), (D) has a fragment because ";" should be followed by an independent clause and not a dependent clause but option D leaves a sentence fragment at the last sentence after the semicolon.

The convent was not born in mexico but Sor Juana was born in Mexico,eliminate A,C and E.

the usage of ';' and then the modifier is wrong because semicolon is ending the clause.elimiate D

B is the correct answer.
