If h2 = 4O. Then h = 6.324.
How it will come 3.3? Please explain.

For slopes greater than 5% the above formula must be adopted otherwise the second part of the formula can be neglected.
Since the first three options are less than or equal to 5% they can neglected as the 3m is greater than 5% the second part of formula must included. Hence the answer is (D) 3m.

When distances are measured along the slope, the equivalent horizontal distance may be determined by applying a slope correction.
The vertical slope angle of the length measured must be measured. (Refer to the figure on the other side).
Thus, For gentle slopes, m<20%.
Ch = h^2/2l.
For steep slopes, 20% <= m <= 30%.
Ch = h^2/2l+h^4/8l^3.
For very steep slopes, m>30%.
Ch = l(1-cos0).

Two things I found in this discussion,
1) For a slope smaller than 10%, Slope correction = h^2/2l, and,
2) For a slope greater than 10%, Slope correction = h^2/2l + h^4/8l^3 should use.
But finally, I did not get the answer 3 or 3.333.
Please anybody explains this answer in detail.
Thanks in advance;).
