• A. $\frac{6}{56}$
• B. $\frac{4}{49}$
• C. $0$

Answer 1

The correct option is D

$1$

$\frac{3}{8}\times \frac{2}{7}\times \frac{8}{3}\times 3\frac{1}{2}$

= $\frac{3}{8}\times \frac{2}{7}\times \frac{8}{3}\times \frac{7}{2}$

= $(\frac{3}{8}\times \frac{8}{3})\times (\frac{2}{7}\times \frac{7}{2})$

= $1\times 1$

= $1$
