Answer #1

Joule is an unit of energy for normal day to day life problems. (SI unit of energy)

Calorie-same. (CGS unit of energy)

Rydberg is used to calculate energy levels in Hydrogen atom. So yes, Rydberg is used when we transition to the very small, but only in a specific area(Hydrogen)

electron volts is the common unit of energy for the "very small"

So if only one option is correct, correct answer will be B.

But if multiple options are correct, B & D are correct.
