Solution

The correct option is D 1 electron pair
Hydrogen has one electron in its valence shell and it needs one more electron to attain the duplet.
Similarly, chlorine has 7 electrons in its valence shell and it needs one more electron to attain the octet.
Hence they will share one electron each to form a single covalent bond and attain stability.
