Question

where should a parenthetical in-text citation be placed?
after the quote and before the period at the end of the sentence
within the quote in the middle of the sentence
before the quote at the very beginning of the sentence

Explanation:

Standard academic citation styles (like APA, MLA) specify that parenthetical in-text citations follow the quoted material, positioned between the end of the quote and the final sentence period to clearly link the source to the referenced content without disrupting sentence structure.

Answer:

after the quote and before the period at the end of the sentence
