Answer:
a) One of the roots in the word counterintuitive is counter-, which means “contrary.”
Explanation:
The compound word "counter-intuitive" means, in simple words, contrary to intuition or commonsense belief. This means it opposes the very intuitive sense of a person, without the need for conscious reasoning.
And when taken separately, "counter" means to contradict something or someone. It simply means "to be opposite of what is implied". And "intuitive" or "intuition" means "a result without conscious reasoning", a result of intuition or simple belief and does not require any reasoning to be deemed true.
So, for the compound word "counter-intuitive", one of the root words is "counter" which means "contrary" or "opposite".
Thus, the correct answer is option a).
