The answer is False: Resistant bacteria will exhibit a large zone of inhibition during a Kirby-Bauer diffusion test.

Explanation:

• In a Kirby-Bauer diffusion test, antibiotics are placed on a culture of bacteria to see how effective they are at inhibiting bacterial growth.
• A "zone of inhibition" is the area around the antibiotic disk where bacteria cannot grow. The size of this zone indicates the effectiveness of the antibiotic.
• Resistant bacteria will not be inhibited by the antibiotic, resulting in a small or nonexistent zone of inhibition.
• Therefore, resistant bacteria will not exhibit a large zone of inhibition; instead, they will show a small or no zone of inhibition.
