If $P = \{a\}$ and $Q = \{b, c\}$ , then $P \times Q =$

a $\{(a, b), (a, c)\}$
b $\{(b, a), (c, a)\}$
c $\{(a, b, c)\}$
d $\varnothing$

ব্যাখ্যা

Each element of $P$ becomes the first coordinate and each element of $Q$ the second. Since $P = \{a\}$ , the pairs are $(a, b)$ and $(a, c)$ , giving $\{(a, b), (a, c)\}$ .
