Solution

The correct option is B They are inversely proportional.
Here, when A = 2, B = 4.
$The product A \times B = 2 \times 4 = 8$

Also when when A = 8, B = 1.
$The product A \times B = 8 \times 1 = 8$

Since the product is the same A and B are in inverse proprotion.

Here, when A = 2, B = 4.
$The product A \times B = 2 \times 4 = 8$

Also when when A = 8, B = 1.
$The product A \times B = 8 \times 1 = 8$
