This question tests the ability to complete a sentence with the clause that follows logically from what has already been stated.

The sentence begins by stating that the speaker is going to the hospital. A hospital is a place people visit specifically for medical reasons, so the continuation that makes sense is one that gives a medical reason for the visit, namely that the speaker is unwell. This connects cause to effect directly: being unwell is the reason for going to a hospital, in the same way going to a place of worship would logically follow a statement about wanting to pray, not about visiting a hospital.

The other options either describe an unrelated destination, an unrelated intention to turn back, or an unrelated errand to buy herbs, none of which follows naturally from the specific statement about heading to a hospital.

For sentence-completion questions, test each option by asking whether it gives a reason, result, or detail that a listener would naturally expect to follow the opening statement, rather than one that is merely grammatically possible.
