Logic Level 2

Once Abhi had a chemistry test on reactivity, that he has not prepared for. He saw the following multiple-choice question, where only one choice was correct.

Which of the following is correct about element A?

1: It is more reactive than element B.
2: It is less reactive than element C.
3: It is less reactive than element D.
4: It is more reactive that element C.

Abhi does not know anything about elements A, B, C or D. Assuming that Abhi is a smart guy and thinks logically, what is the probability that Abhi will get this question correct?

Clarification: No two elements are equally reactive.
