Select the option that is true regarding the following two statements labelled Assertion (A) and Reason (R).

Assertion (A): Bad breath odour experienced on a regular basis is a sign that something is wrong with your health.

Reason (R): Stomach acid reflux is associated with bad breath.

Option D: Both Assertion (A) and Reason (R) are true, and Reason (R) is the correct explanation of Assertion (A).

Assertion (A) states that bad breath odour experienced regularly can indicate an underlying health issue. This is true because chronic bad breath, also known as halitosis, can be a sign of various health problems such as gum disease, dry mouth, or even gastrointestinal issues.

Reason (R) mentions that stomach acid reflux is associated with bad breath, which is also true. Stomach acid reflux, particularly when it reaches the mouth, can lead to an unpleasant odour contributing to bad breath. This occurs because the acid can cause irritation and bacterial growth in the mouth, leading to halitosis.

Therefore, Reason (R) provides a valid explanation for Assertion (A), making both statements true and Reason (R) the correct explanation for Assertion (A).
