What has to increase in order for an object to accelerate?

the mass of the object

the force applied to the object

the weight of the object

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
