Five sentences related to a topic are given below. Four of them can be put together to form a meaningful and coherent short paragraph. Identify the odd one out :

We first try to form a sequence and then pick the odd one out.

The overall idea of the paragraph is to highlight the connection between the muscle and the mind that the scientists have discovered.

Sentence A is a good introductory sentence telling what exactly is being studied by the scientists and talked of, that is, the impact of exercise on the brain.

Sentence B refers to what 'they' have found out from studying the brain and exercise connection, and therefore is the follow-up of A.

The sentence B ends with mentioning a connection being found, and sentence D explains that connection and the impact of muscle movement on our minds. Therefore, D is a follow-up.

The sentence E follows up on shedding light on the factors and their background discussed in sentence D.

Therefore, ABDE is the correct sequence.

Sentence C talks of movement and how we have reduced it in our lives, but it does not fit with the flow of the passage, and putting it anywhere would break the chain of thought and connection. Moreover, it does not touch upon the main premise of the passage, which is the connection between the mind and the muscle. Therefore, C is the odd one out.
