Answer 1

"As an enthusiastic reader, Sanjay often visits the library to check out new books." is correct.

Reason: the introductory phrase "As an enthusiastic reader" should be set off from the main clause with a comma. The version with a dash is punctuated incorrectly, the parenthetical version is awkward and unnecessary, and the version without a comma is missing the standard punctuation after an introductory clause.
