Choice A rationale:

 Poor hygiene.

Poor hygiene is a known risk factor for cellulitis.

Inadequate hygiene practices can lead to an increased risk of skin infections, including cellulitis.

Choice B rationale:

 Diabetes.

Diabetes is a known risk factor for cellulitis.

People with diabetes are more susceptible to skin infections due to impaired immune function and poor circulation.

Choice C rationale:

 Recent surgery or invasive procedures.

Recent surgery or invasive procedures are known risk factors for cellulitis.

These procedures can disrupt the skin's protective barrier, making it easier for bacteria to enter and cause infection.

Choice D rationale:

 Allergic reaction to antibiotics.

This is not a known risk factor for cellulitis.

While allergies to antibiotics can cause various reactions, including skin rashes, they are not considered a direct risk factor for cellulitis.
