Solution

The correct option is B $10 m$
$\frac{H i g h t o f t h e t o w e r}{L e n g t h o f s h a d o w o f t h e t o w e r} = \frac{H i g h t o f t h e t r e e}{L e n g t h o f s h a d o w o f t h e t r e e}$

$⟹ \frac{6}{15} = \frac{H}{25}$

$⟹ H = 25 \times \frac{6}{15}$

$∴ H = 10 m$

OPtion B is correct.
