Explanation:

Step1: Understand bonding electrons

Bonding electrons are involved in chemical - bonds between atoms.

Step2: Analyze each arrow

Arrow a points to a double - bond between C and O, which is a bonding electron pair. Arrow b points to a single - bond between C and H, which is a bonding electron pair. Arrow c points to a non - bonding (lone) electron pair on O. Arrow d points to a single - bond between O and H, which is a bonding electron pair.
