C
662.5×1034 J. sec.

Solution

The correct option is A $$6.625 \times 10^{-34}$$ J. sec.
The Planck's constant is named after the physicist Max Planck. It links the frequency of the electromagnetic wave of a photon to its amount of energy.
         $$E=hv$$
$$h\rightarrow$$ planck's constant $$=6.625\times 10^{-34} J.sec.$$
