Answer is Wrong!
Answer is Right!
The correct answer is B. taut.
Flaccid means “not firm or stiff; limp.” Taut means “tightened or stretched so as to be firm or rigid.” Upright means “standing straight up.” Uneven means “not level or smooth.” Tough means “strong and not easily damaged.”
Of the above options, only
taut is the opposite of flaccid. A taut object is firm and stiff, while a flaccid object is not. The other options do not describe the opposite of flaccid.
