Final answer:

The correct answer is Option b) Bent. This shape has 2 bonds and 2 lone pairs resulting in bond angles close to 104.5° due to LP-BP repulsions.

Step-by-step explanation:

The shape with 2 bonds, 2 lone pairs, and bond angles of 104.5° is known as the bent molecular geometry. This shape is also sometimes referred to as a V-shaped molecule. It is similar to a trigonal planar molecular geometry with a missing vertex due to the presence of lone pairs that result in a decrease of the bond angles to less than 120°, specifically around 104.5°. These effects are due to lone pair-bond pair (LP-BP) repulsions, which influence the shape and angles within the molecule. Therefore, the correct answer to the question is Option b) Bent.
