    Thiophene has the highest resonance energy, dear Reshav. And generally, we don't compare resonance energies of rings of two different numbers.

    Option D is correct As in pyridine π - electrons are involved in providing aromaticity where as other three compounds non-bonding electrons (. lone pair ) are involved which are less available than pi electrons. Thus pyridine has highest delocalization of electrons thus have highest resonance energy.
