Ответ:
The correct option is D) Both B and C.
Explanation:
Mole is defined as the measurement of a substance that contains
a number of particles (atoms, molecules, ions, etc..)
A dozen simply means that there is 12 number of articles like eggs, bananas, etc..
A gaggle is known as the collection of goose.
When an atom is compared with a mole, then an egg will be compared with a dozen, and a goose will be compared with a gaggle.
Thus, an atom is to a mole as an egg is to a dozen and a goose is to a gaggle.
