Solution

The correct option is B
Product

The length of the small rod = 12 cm

The length of the big rod = 0.15 m = 15 cm ( Converting into the same units )

Ratio of the small rod to big rod = $\frac{length of the small rod}{length of the big rod}$

= $\frac{12}{15}$

= $\frac{4}{5}$

Hence the ratio of the length of the small rod to big rod = 4 : 5
