(A) 6
(B) 7
(C) 8
(D) 10
(E) 14


Total Students = 30

Exclusively G1 has = 10 students

Remaining 20 to be placed in other two groups and out of all groups

For maximum students in No Group, The shared students should be maximum between remaining two groups
Maximum Common students between G2 and G3 = 6
G2 will have 4 students exclusively
So total Students assigned in groups = 10+6+4 = 20

Remaining students = 30-20 = 10

Answer: Option D
