(C) The reaction of a mixture of two different alkyl halides with $Na$ metal in dry ether is known as the Wurtz reaction.When a mixture of ethyl bromide $(C_2H_5Br)$ and $n$-propyl bromide $(C_3H_7Br)$ reacts with $Na$ in dry ether,three different alkanes are formed due to the coupling of alkyl radicals:$1$. Coupling of two ethyl radicals: $C_2H_5-C_2H_5$ ($n$-butane)$2$. Coupling of two $n$-propyl radicals: $C_3H_7-C_3H_7$ ($n$-hexane)$3$. Cross-coupling of one ethyl and one $n$-propyl radical: $C_2H_5-C_3H_7$ ($n$-pentane)Thus,a total of $3$ different alkanes are formed.

When ethyl bromide and $n$-propyl bromide are allowed to react with $Na$ metal in dry ether,the number of different alkanes formed is
