C. corpus luteum
D. corpus allatum

Explanation

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks for a temporary endocrine gland in the human body. We need to identify which of the given options fits this description.

2. **Analyzing the Options**:
- **Option 1: Pineal Gland**: This is a small, permanent endocrine gland located in the brain. It produces melatonin, which regulates sleep patterns. Therefore, it is not a temporary gland.
- **Option 2: Corpus Cardiacum**: This is an organ that stores neurosecretory products but is not classified as an endocrine gland in humans. It is more relevant in insects, so this option is also incorrect.
- **Option 3: Corpus Luteum**: This is a temporary endocrine gland that forms in the ovaries after ovulation. It secretes hormones like progesterone and estradiol, which are crucial for maintaining pregnancy. If fertilization does not occur, the corpus luteum degenerates, confirming its temporary nature.
- **Option 4: Corpus Allatum**: This is another endocrine gland found in insects, responsible for producing juvenile hormone. It does not pertain to human physiology.

3. **Identifying the Correct Answer**: Based on the analysis, the only option that qualifies as a temporary endocrine gland in the human body is the **Corpus Luteum**.

4. **Final Conclusion**: Therefore, the correct answer to the question is the **Corpus Luteum**.
