Thanks for asking the question!

ANSWER::

√x = t + 1

Squaring both sides

(√x)² = (t + 1)²

x = t² + 2t + 1

Now , lets apply differentiation

dx/dt = (d/dt)(t² + 2t + 1) = 2t + 2

Now , we will put some values in t to check which option is right.

We won't take t values negative because time cannot be negative.

v(t) = 2t + 2

v(0) = 2(0) + 2 = 2

v(1) = 2(1) + 2 = 4

v(2) = 2(2) + 2 = 6

After putting values we can see that the velocity is increasing as time increases .

(a) Increases with time will be the answer.
