Correct answer is (c) Magnesium hydroxide
\(\underset{\text{Magnesium ribbon}}{2Mg} + \underset{\text{oxygen}}{O_2}\) \(\overset{\text{burn}}{\longrightarrow}\, \underset{\text{Magnesium oxide}}{2MgO}\)
due to, wet watch glass, MgO reacts with H2O and form magnesium hydroxide -
\(MgO\, + H_2O\, \longrightarrow \, \underset {\text{Magnesium Hydroxide}}{Mg(OH)_2}\)
