![F = ma](https://img.qammunity.org/2020/formulas/physics/high-school/6dslirwz7efajuroewtnbxamr1m7rpia2b.png)
so here all the cases where object is accelerating then it means it is followed by some external force on it
so here we have
A - Accelerating a car from a stop sign
C - Lifting a chess pics off a board
D - Throwing a ball
all above cases objects are accelerating so it shows net force on them
while correct answer for no force on the object is
B - Driving straight down the highway at 60 mph
