If set A={Φ} then P(A) is ___________(a) {Φ}(b) {{Φ}}(c) {Φ, {Φ}}

1.	If set A={Φ} then P(A) is ___________(a) {Φ}(b) {{Φ}}(c) {Φ, {Φ}}(d) ΦThe question was asked during an online interview.My doubt stems from Power Sets topic in section Sets of Mathematics – Class 11
Answer» CORRECT answer is (C) {Φ, {Φ}} To EXPLAIN I would SAY: Set A={Φ} => Set A has one element Φ so, SUBSETS of set A are Φ, {Φ}. So, P(A) = {{Φ, {Φ}}.
