Solution

The correct option is A 25 $^{0} C$
Given,

Temperature $T_{1} = 0^{o} C$ and height $h_{1} = 50 c m$

Temperature $T_{2} = 100^{o} C$ and height $h_{2} = 90 c m$

$\frac{T - T_{1}}{h - h_{1}} = \frac{T_{2} - T_{1}}{h_{2} - h_{1}}$

$\frac{T - 0}{60 - 50} = \frac{100 - 0}{90 - 50}$

$T = 25^{o} C$

Hence, at $60 c m$ , temperature is $25^{o} C$
