Solution

Solution Steps

Step 1: Identify the atoms and their bonding

Atom a: Nitrogen (N) with three single bonds and one lone pair.
Atom b: Carbon (C) with three single bonds and no lone pairs.
Atom c: Carbon (C) with two single bonds and one double bond.
Atom d: Carbon (C) with four single bonds.

Step 2: Determine the electron geometry for each atom

Atom a: Nitrogen (N) with three bonds and one lone pair has a trigonal pyramidal geometry.
Atom b: Carbon (C) with three bonds has a trigonal planar geometry.
Atom c: Carbon (C) with three bonds (one double bond and two single bonds) has a trigonal planar geometry.
Atom d: Carbon (C) with four single bonds has a tetrahedral geometry.

Step 3: Match the geometries to the given options
