Statement-1: In case of pure atomic orbitals overlap having same internuclear distance the relative strength order is $\mathrm{s}-\mathrm{s}>\mathrm{s}-\mathrm{p}>\mathrm{p}-\mathrm{p}$.

Statement-2: The radial distance of $\text{'}\mathrm{s}\text{'}$-orbital is less compared to that of $\mathrm{p}$-orbital for a particular value of principal quantum number.

Statement-1 is false, statement-2 is true.

Statement-1 is true, statement-2 is false.

Statement-1 is true, statement-2 is true and statement-2 is NOT the correct explanation for statement-1.

Statement-1 is true, statement-2 is true and statement-2 is correct explanation for statement-1.
