(C) should be the appropriate one.
a = dv/dt = slope (And here we would also consider the amgnitude)
First divide the v-t grapgh into 4 – intervals.
First Interval –> the slope is -ve and magnitude is positive => multiplication would give -ve answer.
Hence the graph would start from negative side.
 
Second interval => slope is negaive plus magnitude is also negative would make positive accln.
 
Third interval → slope is positive plus magnitude is negative hence negative accln.
 
Fourth interval → slope and magnitude both are positve and hence would give the multiplication as positive.
 
Hneece 3rd option is correct.
