In each question consist of five statements (a-e) followed by options consisting of three statements put together in a specific order. Choose the option which indicates a valid argument, that is, where the third statement is a conclusion drawn from the preceding two statements.

a. law graduates are in great demand.
b. Rajesh and Krishna are in great demand.
c. Rajesh is in great demand.
d. Krishna is in great demand.
e. Rajesh and Krishna are law graduates.

Choose the correct option:

The correct option is a e b.

To determine which option indicates a valid argument, we need to check if the third statement logically follows as a necessary conclusion from the first two statements acting as premises.

Let's analyze the statements given in the option a e b step-by-step:
Premise 1 (Statement a): Law graduates are in great demand.
Premise 2 (Statement e): Rajesh and Krishna are law graduates.
Conclusion (Statement b): Rajesh and Krishna are in great demand.

Logical Breakdown:
1. From Premise 1, we know that any individual who is a law graduate falls into the category of being in great demand.
2. From Premise 2, we are given that both Rajesh and Krishna are law graduates.
3. Combining Premise 1 and Premise 2, since Rajesh and Krishna belong to the group of law graduates, and all law graduates are in great demand, it logically follows without doubt that Rajesh and Krishna are in great demand (Statement b).

Therefore, the sequence a e b forms a perfectly valid logical syllogism where statement b is a valid conclusion drawn from preceding statements a and e.
