(a) Bird
(b) Moth
(c) Bat
(d) Butterfly

Options

A. Bird
B. Moth
C. Bat
D. Butterfly.

Answer

To determine which pollinator is not attracted by the scent of flowers, we will analyze each option provided:

1. **Bird (Option A)**:
- Birds, particularly hummingbirds, are often attracted to flowers, but they primarily rely on visual cues (such as bright colors) rather than scent. However, some bird species may still respond to floral scents.

2. **Moth (Option B)**:
- Moths are nocturnal pollinators that are typically attracted to the scent of flowers. They have a strong sense of smell and are drawn to fragrant flowers, especially those that bloom at night.

3. **Bat (Option C)**:
- Bats are also known to be attracted to the scent of certain flowers, particularly those that are white or pale-colored and bloom at night. They rely on both scent and echolocation to find flowers.

4. **Butterfly (Option D)**:
- Butterflies are attracted to flowers primarily for their nectar and are also drawn to the scent of flowers. They have a keen sense of smell that helps them locate flowers.

Based on the analysis above, the correct answer is **(a) Bird**, as they are less reliant on scent compared to the other pollinators listed.

### Final Answer:
(a) Bird
