Solution
The correct option is A Statement-1 is true, Statement-2 is true; Statement-2 is a correct explanation for Statement-1 Both sodium and hydrogen is having same outer electronic configuration ns1 but hydrogen have less reactivity because the ionization potential of Na is less. Hence, it can loose its electron easily and participates in chemical reaction easily, so reason is the correct explanation for assertion so option A would be correct.
