Explanation:

A base is defined as the substance which releases hydroxide ion when dissolved in water.

For the given options:

When ammonia is dissolved in water, it produces ammonium hydroxide which forms a basic solution.

$NH_3+H_2O\rightarrow NH_4OH$

Option 2: $Na_2O$

When sodium oxide is dissolved in water, it produces ammonium hydroxide which forms a basic solution.

$Na_2O+H_2O\rightarrow 2NaOH$

Option 3: $LiOH$

When lithium hydroxide is dissolved in water, it produces aqueous lithium hydroxide which forms a basic solution.

$LiOH+H_2O\rightarrow LiOH(aq.)$

Option 4: $P_4O_{10}$

When phosphorus pentoxide is dissolved in water, it produces phosphoric acid which forms an acidic solution.

$P_4O_{10}+6H_2O\rightarrow 4H_3PO_4$
