Yes, C is right answer.

I think you did not understand what Retaining wall and its Function.

How can you decide 1:3? the Battering Slope is decided by According to the Standard which means that;

If the Battering slope 1:2, 1:3 or 1:4 . . . . . .. . .
Safe among the Overturning, Safe among Sliding.
Then we will Choose the battering slope any one of them.
Anyhow, For a given Highway to construct Any Masonry Retaining Wall we should make. Structural Analysis of the wall safe among Overturning, Sliding.

If, 1:2 is safe among those then we well choose the batter slope.

Yes, right @Haylee.

Option c is correct. Also the design of retaining wall is done on THUMB RULE. Detailed structural analysis is not required.

The design if a retaining wall needs structural analysis definitely. But to proceed with at the beginning we apply thumb rule to get preliminary dimensions with respect to the height of the retaining wall. During such proportioning, we take a batter of 1:3. This can change during actual designing. If batter required is steeper then we keep this value. But if batter required is flatter then we accept the flatter one or sometimes we adjust the top width to make the batter proportionate and look presentable geometrically.
