In the following question, Assertion (A) is given followed by a statement of Reason (R). Choose the correct answer.
Assertion (A): \(\pi\left(2 p_x\right), \pi\left(2 p_y\right), \pi^*\left(2 p_x\right), \pi^*\left(2 p_y\right)\) molecular orbitals have one nodal plane each.
Reason \((\mathrm{R})\) : All the molecular orbitals formed by the sideways overlapping have one nodal plane.

1. A Both assertion and reason are true and reason is not the correct explanation of the assertion.
2. B Both assertion and reason are true and reason is the correct explanation of the assertion.
   
3. C Assertion is true but reason is false
   
4. D Both assertion and reason are false
