Let $\Omega$ be the sample space and $A \subseteq \Omega$ be an event. Given below are two statements:
$(S1) : \text{If } P(A) = 0, \text{ then } A = \phi$
$(S2) : \text{If } P(A) = 1, \text{ then } A = \Omega$
Then:

• A
  only $(S1)$ is true
• B
  only $(S2)$ is true
• C
  both $(S1)$ and $(S2)$ are true
• D
  both $(S1)$ and $(S2)$ are false
