I believe the answer is B. Water can accept a proton to become a hydronium ion, or donate a proton to become a hydroxide ion.
When water accept aproton, it will create this equation:
H2O + H+ -> H3O+       . . . . (H3O+ is the hydronium ion)

When water donate proton. it will create this chemical equation:
H2O -> H+ + OH-   . . . . . .  (OH- is the hydroxide ion)
