Consider the following statements: Assertion (A): the plane y + z + 1 = 0 is parallel to the x-axis. Reason (R): normal to the plane is parallel to the x-axis. Of these statements:

Both A and R are true and R is the correct explanation of A Both A and R are true and R is not a correct explanation of A A is true but R is false A is false but R is true

A is true but R is false

The given plane y + z + 1 = 0 is parallel to the x-axis as 0.1 + 1.0 + 1.0 = 0 but normal to the plane will be perpendicular to the x-axis. Hence (C) is the correct answer.
