Answer 1

The correct option is A Mean proportion

(A) mean proportion

Since we are given; $a,b$ and $c$ are in continuous

Proportion, this means;

$a:b::b:c$

$\Rightarrow$ Product of extremes = Product of means

$\Rightarrow a\times c=b\times b$

$a\times c=b^2$

$\therefore b$ is the mean Proportion.
