The circle around choice-c is the correct choice.
The formula written in pencil under the question is the correct formula.
BUT, when you use it, you have to be careful with the signs.
V₀ is the initial speed of the toss. That's the 49 m/s, and it's
positive, because the ball is tossed upwards.
The 'a' is the acceleration of gravity ... 9.8 m/s² ... and that's
negative, because gravity accelerates things downward.
So, to apply the formula properly, it would be
D = (49 m/s) (5 sec) + (1/2) (-9.8 m/s²) (5 sec)²
= ( 245 m ) + ( -4.9 m/s² ) (25 sec²)
= ( 245 m ) - ( 122.5 m)
= 122.5 m
