Solution

The correct option is B
&

For the given ratios to be in proportion , product of means = product of extremes

Given numbers are 7 , 81 ,3 and 49

We have product of means = $81 \times 3 = 243$

Product of extremes = $49 \times 7 = 343$

Since $243 \neq 343$ The given ratios are not in proportion
