A vector is described by $\overrightarrow{A}$$=A_x\hat{i}+A_y\hat{j}+A_z\hat{k}$, then $A_y$ is a scalar.

Reason (R) : The projection of a vector is a scalar

A is incorrect and R is correct

Both A and R are correct and R is the correct explanation of A

Both A and R are correct , but R is not the correct explanation of A

A is correct and R is incorrect
