Answer 2

Answer:

the answer is (c) 12 x 3

Step-by-step explanation:

• if we see there are total 3 rows os each and every row has 6 students.
• if a student can take any place in the array , therefore its between 2 students to change their respective position.
• there are 6 students in each row , therefore

                        2 x 6 = 12

• here we take only 2 students in teh place of 3 from each row is because if one hast to change then another student has to change its place but the 3rd one remains same , by that cause we use only 2.
• Now there are 12 possibilities and there are total 3 rows  therefore,

               12 x 3

  Hence, there are 12 x 3 different arrangements ae posible.
