Best answer
The correct option is (a) True

The explanation: In smooth cast finish, steel floats are not recommended for external renderings. Instead, a wooden float is used for applying the mortar. This is because steel floats give a very smooth finish which is very likely to crack when exposed to atmospheric conditions.
