Measured length(along axis) = L= KScosθ.
Actual length = L' = KScos(θ±δ),
Error per unit length = (L-L')/L.
Actual length = L' = KScos(θ±δ),
Error per unit length = (L-L')/L.

E is an error. The staff reading component on the normal (true) axis will be +/- cos δ. Hence the expression governed by cosine values, that is Option A.

@Abhi.
It means in both cases we have to take angle positive.
