(a) A simple pendulum.
(b) A physical pendulum.
EXPLANATION:
Since on the moon g changes, only that time period will change which depends on the value of g. The time period of a simple pendulum and the physical pendulum is a function of g so their time period will change on the moon. (a) and (b) are true. The time period of a torsional pendulum and the spring-mass system is not dependent on the value of g, so they will not change on the moon. (c) and (d) not true.
