The following bar graph shows the marks (out of 100) of students A, B, C, D, E and in the subjects mentioned.

Based on this, only 2 students crossed the average marks in the subject:

From the bar graph,

Average marks of students in Maths = $$\frac{86+69+60+70+78+92}{6}=\frac{455}{6}=75.834$$

Average marks of students in Economics = $$\frac{98+58+70+80+73+74}{6}=\frac{453}{6}=75.5$$

Average marks of students in Commerce = $$\frac{76+66+84+65+82+68}{6}=\frac{441}{6}=73.5$$

Average marks of students in Civics = $$\frac{96+75+78+83+93+87}{6}=\frac{512}{6}=85.34$$

$$\therefore\ $$Only 2 students crossed the average marks in the subject Economics

Hence, the correct answer is Option D
