### Break Down the Problem
1. Identify the main subject of the sentence to determine the correct verb form.
2. Analyze the context to understand the meaning conveyed and how the options change that meaning.

### Relevant Concepts
- Subject-verb agreement is essential in English grammar, which means that the verb must agree in number with its subject.
- The phrase “program that funds hundreds of space explorations” indicates the subject is singular (“program”) but introduces a plural noun (“explorations”).

### Analysis and Detail
1. **Option A: NO CHANGE**
- This keeps the sentence as it is: "The program that funds hundreds of space explorations are losing half its funding."
- Incorrect because "program" (singular) does not agree with "are" (plural).

2. **Option B: exploration is**
- Changes the sentence to "The program that funds hundreds of space exploration is losing half its funding."
- This maintains subject-verb agreement ("program" is singular and so is "is"). However, "space exploration" as a singular concept may not accurately reflect the original meaning.

3. **Option C: explorations is**
- Changes the sentence to "The program that funds hundreds of space explorations is losing half its funding."
- Here, though "explorations" is plural, it still maintains subject-verb agreement because "is" applies to "program" which is singular. This is logically consistent with the idea of multiple space explorations.

4. **Option D: exploration, is**
- Changes the sentence to "The program that funds hundreds of space exploration, is losing half its funding."
- This incorrectly punctuates the clause, leading to confusion about the subject and verb.

### Verify and Summarize
- The correct version requires the subject to match the verb unintentionally in number.
- Options B and C maintain agreement; however, C best conveys the intended meaning while avoiding ambiguity.

### Final Answer
The best option is **C: explorations is**. The revised sentence reads: "The program that funds hundreds of space explorations is losing half its funding." This maintains subject-verb agreement and effectively communicates the intended idea.
