Thank you for asking this question. The options for this question are missing:

A. 190

B. 200

C. 210

D. 220

E. 225

Answer:

The correct answer for this question is Option C: 210

A plays with B is same as B plays with A. So it is counted as two times playing (i.e they are playing against each other twice.)

3 x 2 = 6 games

So for 15 persons, its 15 x 14 = 210
