When fungal spores land on a piece of bread left on a table then after a few days, the bread becomes mouldy. What conditions favour the growth of the fungus?
I. The presence of food
II. The moist temperature
III. The absence of water

Options

A. I only
B. I and II
C. II and III
D. I, II and III

Explanation

To determine the conditions that favor the growth of fungus on a piece of bread, we need to analyze each of the given options:

1. **The presence of food**: Fungi are heterotrophic organisms, meaning they cannot produce their own food and rely on external sources. Bread provides a suitable source of nutrients for the fungi, making this condition favorable for their growth.

2. **The moist temperature**: Fungi thrive in moist environments. High moisture levels help fungi to grow and reproduce effectively. Therefore, a moist temperature is indeed a condition that favors fungal growth.

3. **The absence of water**: This condition is not favorable for the growth of fungi. Fungi require moisture to grow, and the absence of water would hinder their development. Therefore, this option is incorrect.

Based on this analysis, the correct conditions that favor the growth of fungus on bread are:
- I. The presence of food (Correct)
- II. The moist temperature (Correct)
- III. The absence of water (Incorrect)

### Final Answer:
The conditions that favor the growth of the fungus are:
- I. The presence of food
- II. The moist temperature
