C

Step-by-step explanation:

Cross section means looking at an object from where it was cut. If you imagine looking at the cube with the cylinder cut from it's center from where it was cut at, you would see that it basically resembles a square with a indent in the middle. Hopefully this makes sense to you.

solution:

→c= a b , that is product of a and b is possible only when when a is m × n matrix and b is n × p matrix.

that is, number of columns of a= number of rows of b.

so, size of matrix , c= a b is , if a = (m × n)matrix

b= (n × p)matrix

then a b = [ (m × n)matrix] ×[   (n × p)matrix ]

→→c= a b= [m × p ] matrix

→→size of product a b will be equal to = number of rows of a × number of columns of b
