Answer:
C.12
Step-by-step explanation:
Because 60+72 is 132
132 students in 10 columns has a remainder (remaining students not in a row)
132 students in 11 columns its an exact number but not the greatest number in a row
132 students in 12 columns is the answer because it has an exact number , no remainders and the greatest number of pupils in a row
132 in 13 columns (has a remainder like 10)
