Fungal SCP is not suitable for human consumption because of
(I) High MG (II) Low protein
(III) Mycotoxins
(IV) High percentage of RNA

Options

A. I and II
B. ii and iii
C. iii and iv
D. II and IV

Answer

To determine why fungal Single Cell Protein (SCP) is not suitable for human consumption, we can analyze each of the given options:

1. **Understanding Fungal SCP**: Fungal SCP refers to protein derived from fungi. While fungi can be a source of protein, certain factors can make them unsuitable for human consumption.

2. **Evaluating the Options**:
- **(I) High MG**: This option is unclear without context. "MG" could refer to various things, but it is not a commonly recognized reason for the unsuitability of fungal SCP.
- **(II) Low Protein**: Fungal SCP is generally known for being high in protein content, so this option is not valid.
- **(III) Mycotoxins**: Mycotoxins are toxic compounds produced by fungi. These toxins can be harmful to humans and are a significant reason why fungal SCP may not be safe for consumption.
- **(IV) High percentage of RNA**: Fungi often contain high levels of RNA, which can lead to issues such as digestive problems in humans.

3. **Conclusion**: Based on the evaluation, the two main reasons fungal SCP is not suitable for human consumption are:
- High mycotoxins (III)
- High percentage of RNA (IV)

Thus, the correct answer is (III) and (IV).

### Final Answer:
Fungal SCP is not suitable for human consumption because of:
- (III) Mycotoxins
- (IV) High percentage of RNA
