Read the following statement:

A manager seeks approval for conducting a training programme on 'openness'. He puts forward the following arguments in favour of the program to his CEO.

Which of the following arguments is the least likely to have a logical fallacy?

Option A: Since a group of employees attended the program, a change in the openness of only one participant does not give much incentive to the CEO to give the approval. Thus, this is not the correct option.

Option B: Although this option speaks well of the programme, it does not provide any evidence of the efficacy of the programme. Thus, this is not the correct option.

Option C: Since this option provides consolidation to the efficacy of the program, this is the correct answer. This option is the least likely to have a logical fallacy, as it refers to internal studies that suggest a causal link between 'openness' and a desirable outcome (increased innovation). While the quality of these studies is unknown, the argument attempts to use evidence rather than relying on anecdotes, authority, false choices, or emotional appeals.

Option D: Giving his CEO an ultimatum is not a good idea for the approval. Thus, this is not the correct option.

Option E: Emotional appeal will have a similar effect as that of the previous option. Thus, this is not the correct option.

Thus, the correct option is C.
