The following graph gives the performance of five students A, B, C, D, E in Math, Physics and Chemistry.

Based on the given information - considering that a performance is based on the difficulty level of the paper, which of the following statements is correct?

From the graph,

Score of E in maths is greater than score of B in maths, hence option A is incorrect

Score of D in all subjects are different so the difficulty level is different for all subjects for D, hence option C is incorrect

Score of C in maths is the least so maths is the difficult subject for C and score in physics is the highest so physics is the easiest subject for C, hence option D is incorrect

Score of C in physics is greater than score of B and E in physics, hence option B is correct
