Feasible Group Selection Explanation:

To determine the feasible group of four, we need to consider the preferences and conditions mentioned for each individual. Let's analyze the conditions and preferences step by step.

1. Ram's preference:
- Ram would not like to be in the group if Shyam is also selected.
- Ram would like to be in the group only if Peter is also there.

2. Shyam and Rahim's preference:
- Shyam and Rahim want to be selected together in the group.

3. Kavita's preference:
- Kavita would like to be in the group only if David is also there.

4. David's preference:
- David, if selected, would not like Peter in the group.
- David insists that Fiza be selected in case he is there in the group.

Based on these conditions and preferences, let's evaluate the feasible group options:

a) Ram, Peter, Fiza, Rahim
- Ram prefers to be in the group only if Peter is also there.
- However, Rahim is included in this group, and Shyam cannot be selected along with Rahim as per Ram's preference.
- Therefore, this group is not feasible.

b) Shyam, Rahim, Kavita, David
- Shyam and Rahim want to be selected together, so they are included in the group.
- Kavita wants to be in the group only if David is there, and David is also included.
- This group satisfies all the preferences and conditions mentioned.
- Therefore, this group is feasible.

c) Shyam, Rahim, Fiza, David
- Shyam and Rahim want to be selected together, so they are included in the group.
- Fiza is included as David insists on her selection.
- However, David does not want Peter in the group, and Peter is not included in this group.
- Therefore, this group is not feasible.

d) Fiza, David, Ram, Peter
- David insists on Fiza's selection, so she is included.
- Ram wants to be in the group only if Peter is also there, and both are included.
- However, Shyam and Rahim are not included, which contradicts their preference.
- Therefore, this group is not feasible.

Among the given options, the only feasible group of four is:
b) Shyam, Rahim, Kavita, David
