Solution

The correct option is B
240 m

The ratio of the increase is given by Present Height : New Height = 5 : 6

Hence $5 : 6 = \frac{P r e s e n t H e i g h t}{N e w H e i g h t}$

Present Height = 200 m

$\frac{5}{6} = \frac{200}{N e w H e i g h t}$

$5 \times N e w H e i g h t$ = $6 \times 200$

$N e w H e i g h t = \frac{6 \times 200}{5} = 240 m$
