Correct answer choice is :

B) Their atoms have an identical mass.

Explanation:

Every oxygen molecules have 8 protons, but the nucleus may include 8, 9, or 10 neutrons. Light oxygen16, with 8 protons and 8 neutrons, is the usual normal isotope seen in life, accompanied by many minor numbers of heavy oxygen18, with 8 protons and 10 neutrons.
