D. All the above

Answer

To solve the question "Asexual reproduction takes place by conidia formation in:", we can follow these steps:

### Step 1: Understand Asexual Reproduction in Fungi
Asexual reproduction in fungi can occur through various methods, including the formation of conidia. Conidia are a type of asexual spore that is produced by certain fungi.

**Hint:** Recall the different types of asexual reproduction methods in fungi.

### Step 2: Identify the Organisms Listed
The options given are:
1. Aspergillus
2. Penicillium
3. Cholerotrichum
4. All of the above

**Hint:** Familiarize yourself with the reproductive methods of each of these fungi.

### Step 3: Analyze Each Option
- **Aspergillus:** This fungus can reproduce asexually through conidia.
- **Penicillium:** This fungus is well-known for reproducing asexually by forming conidia.
- **Cholerotrichum:** This fungus also reproduces asexually, but it is less commonly discussed in terms of conidia formation.

**Hint:** Consider the most commonly recognized fungi for conidia formation.

### Step 4: Determine the Correct Answer
Since all three fungi listed (Aspergillus, Penicillium, and Cholerotrichum) can reproduce asexually by forming conidia, the correct answer is option 4: All of the above.

**Hint:** Think about whether the question asks for a specific fungus or if it encompasses multiple fungi.

### Final Answer
The correct answer is **option 4: All of the above**.
