Step-by-step explanation:

  \bold{ \textit{ \colorbox{green}{✅ \: Verified answer }}}

   \huge{\mathfrak{ \boxed{  \color{red} \colorbox{gray}{Given :-}}}}

 \bull \: diameter  \: of  \: circle ,d= 4.2 \: cm

 \implies \: radius = 2.1 \: cm

 \mathtt{We  \: know \:  that}

circumference \:  of \:  circle = 2\pi :r

 \implies  \not2 \times  \frac{22}{  \not7}  \times   \frac{ \not21 \:  ^{3} }{ \not10  \: ^{5} }

 \implies \frac{3 \times 22}{5}

 \implies \frac{ \not66 \:  ^{13.2} }{ \not5}

  \implies \boxed{13.2 \: cm \: }

Hence it's circumference Will be 13.2 cm, hence option (a) is correct one.
