The correct option is B $42$ pizzas

$\text{Fraction of pizza for each person =}\frac{3}{8}$

112 people atended the party.

$\text{∴ Number of pizzas Ali needed =}112\times \frac{3}{8}$

$=112\times \frac{3}{8}$

$=\frac{112\times 3}{8}$

$=\frac{336}{8}$

$=42$

Hence, Ali needed 42 pizzas for 112 people.
