Answer:
B
Explanation:
For an object to accelerate the force on it must be increased
According to Newton's second law of motion
F=ma
Where F is force, m is mass and a is acceleration
Hence keeping the mass constant F is directly propotional to acceleration
Which means if the force increases, acceleration increases and vice versa.
While mass and weight aren't related to motion
And one more thing mass is always constant it can't be changed
