No compensation is required for less than 4 per cent.
So, the answer 3% is correct.
So, the answer 3% is correct.

If the curve provided is <40 then use the formula 30+R/ 30.
And if curve>40 then use the formula 75/R.
Here we use the latter one;.
Now, 75/300 = 0.25.
Compensated G= 3-0.25 = 2.75.
Answer C is correct.

Answer C is correct.

Grade compensation = min (30+r/r or 75/r).
Here 75/r = 0.25.
Gradient = ruling gradient - grade compensation.
= 3.00 - 0.25.
= 2.75.
Here 75/r = 0.25.
Gradient = ruling gradient - grade compensation.
= 3.00 - 0.25.
= 2.75.
