To identify which sentence is written in the subjunctive mood, we need to understand what the subjunctive mood is. The subjunctive mood is used to express a hypothetical situation, a wish, a demand, or something doubtful. It often involves statements that are contrary to reality or express a feeling of uncertainty.

Now let's analyze the given sentences:

A. "If the sun is shining, then I will wear sandals."
This sentence is written in the indicative mood because it states a fact: if the sun is shining, then the person will wear sandals.

B. "It was the weekend, so she slept until noon."
This sentence is written in the indicative mood as well because it describes a past event that actually happened. It does not indicate any hypothetical or doubtful situation.

C. "My health teacher recommends that I eat five servings of vegetables per day."
This sentence is written in the subjunctive mood. The use of the verb "recommends" indicates that it is a suggestion or a wish, rather than an actual statement of fact. Additionally, the phrase "that I eat" suggests a hypothetical or desired action.

Based on this analysis, your answer of sentence C is correct. Well done!
