Step 1: Identify the signs required to reach the food court while using a wheelchair.
- Since you are on a wheelchair, accessibility and navigation signs are important.
- You need to find an elevator suitable for wheelchairs and a sign indicating the food court.
Step 2: Analyze the given signs.
- Option P: Represents a general elevator, but does not specifically indicate wheelchair accessibility.
- Option Q: Represents an elevator with wheelchair accessibility, which is essential.
- Option R: Represents a water facility, which is not necessary for reaching the destination.
- Option S: Represents restrooms, which may be useful but are not required for reaching the food court.
- Option T: Represents food and dining, indicating the food court location.
- Option U: Represents an escalator, which is not suitable for wheelchair users.
Step 3: Identify the correct choices.
- The most relevant signs are Q (Wheelchair-accessible elevator) and T (Food court).
- Other signs such as R, S, and U are not necessary to reach the food court.
Thus, the correct answer is option C.
