|
doubles
|
|
|
quadruples

Explanation:
Detailed explanation-1: -The correct option is C Doubled.
Detailed explanation-2: -If the velocity of a body is doubled then its momentum doubles because velocity is directly proportional to momentum.
Detailed explanation-3: -As the velocity of the object is doubled the momentum of the object also gets doubled.
Detailed explanation-4: -Therefore, when the object’s speed doubles, its kinetic energy doubles to four times the initial kinetic energy.
