Answer 1

Correct choice is (c) Total surface area of the flask

Explanation: The “T” referred to the total surface area of the flask that was available for cell growth: thus a T-25 flask had a 25cm^2 growth area. By the 1960s, straight neck T-flasks was available molded from polystyrene that was treated to enhance cell attachment.
