Answer:
c. hydrogen bonding.
Explanation:
Hydrogen bonding occurs when hydrogen is covalently bonded to a highly electronegative atom such as oxygen, flourine, nitrogen etc.
Hydrogen bonds are quite strong and are known to lead to elevated boiling points. As a result of hydrogen bonding, ammonia is known to have a high melting and boiling point compared to its relative molecular mass.

I know I got this wrong</span>
A) Ca, Mg, Be
The first ionization energy increases as we move up a group because of the smaller atomic size and less shielding of electrons.

if you add or subtract a neutron from an atom it will become a new isotopes of the same element
And the answer is False,it does not have the same number with particles as the one mole of hydrogen.
