Answer 2

Answer:(c) BF3

Explanation: The molecule (a), (b) and (d) are not electron deficient as they have completed their octet/ have enough electron to rich the noble gas configuration. In BF3, the boron atom has 3 electrons in its outer most shell and to complete an octet it needs to have 5 more electrons. But the boron in this molecule is only attached to another 3 electron from the fluorine atoms, which are also highly electronegative.
