Answer:

a) variable

Explanation:

for any graph , if the slope is'nt a straight line ,it means the slope varies at different points. The slopes of such graph is figured out making tangents.

If velocity -time graph of a curve ( given which is not a straight line) has its tangent vary at different points  . Let us know about acceleration.

Acceleration : The rate of change of velocity with respect to time is known as acceleration. It is  denoted as A= dv/dt or Δv/Δt

where v = velocity and t = time and d or Δ denotes  change in measurements.

Considering a curve graph of velocity -time graph , we can say tangent vary i.e.

=>   Tangent = Acceleration = dv/dt = variable
