Solution

The correct option is C $5$ cm
In a triangle, sum of two sides $>$ third side.
So, if two sides are $4 c m$ and $7 c m$ , then considering the given options,
A. $11 c m$
$4 + 7 ≯ 11$

Hence, this is not the correct option.
B. $6 c m$
We see that
$4 + 7 > 6$
$4 + 6 > 7$
$7 + 6 > 4$
Hence, $6 c m$ is the correct option.
