2. I know exactly where to start my research: the library.
Explanation:
1. The semicolon is properly used in the right option to join two independent clauses closely related in meaning. In the first and last options, a semicolon is used where a colon would have been correct. In the third option, the adverb clause "if the records..." should be separated from the main sentence with a comma, not a semicolon.
2. In the right option, a colon is properly used to introduce a sentence or phrase that illustrates or complements the previous. Semicolons are wrongly used in the first and last options, needlessly setting off a complement, while in the third option, a semicolon (not a colon) should be used to join the two independent clauses.
