C. Progesterone
D. Testosteron

Answer

To answer the question "Hormone which is responsible for maintenance of corpus luteum is:", we can follow these steps:

### Step 1: Understand the Corpus Luteum
The corpus luteum is a temporary endocrine structure formed in the ovary after ovulation. It is derived from the ruptured follicle that releases an egg.

**Hint:** Remember that the corpus luteum forms after the ovulation process.

### Step 2: Identify the Function of the Corpus Luteum
The primary function of the corpus luteum is to secrete hormones that are crucial for maintaining pregnancy. It produces hormones that support the early stages of pregnancy.

**Hint:** Think about what happens after ovulation and how the body prepares for a potential pregnancy.

### Step 3: Know the Hormones Involved
The key hormones produced by the corpus luteum include progesterone and estrogen. However, the hormone specifically responsible for maintaining the corpus luteum itself is progesterone.

**Hint:** Focus on the role of progesterone in pregnancy and its specific function in maintaining the corpus luteum.

### Step 4: Evaluate the Options Given
The options provided are:
1. Estrogen
2. Aldosterone
3. Progesterone
4. Testosterone

- **Estrogen**: While it is produced by the ovaries and plays a role in female secondary sexual characteristics, it is not the primary hormone for maintaining the corpus luteum.
- **Aldosterone**: This hormone is involved in sodium reabsorption and does not relate to the corpus luteum.
- **Progesterone**: This is the correct hormone that maintains the corpus luteum and supports pregnancy.
- **Testosterone**: This is the male sex hormone and is not involved in the maintenance of the corpus luteum.

**Hint:** Compare each hormone's function with the role of the corpus luteum to identify the correct answer.

### Step 5: Conclusion
Based on the information and analysis, the hormone responsible for the maintenance of the corpus luteum is **progesterone**.

**Final Answer:** Progesterone
