To write a Python Program to perform Matrix Multiplication.

Question 1: Which of the following matrices will throw an error in Python?

[[1, 2, 3],[4, 5, 6],[7, 8, 9]]
[[3, 3, 3] [4, 4, 4] [5, 5, 5]]
[(1, 2, 4),(5, 6, 7),(8, 9, 10)]
[2, 3, 4, 3, 3, 3, 4, 5, 6]

Question 2: If A is a matrix of order m*n , B is matrix of order n*p then what is the order of AB matrix?

p*m
p*n
m*n
m*p

Question 3: Consider the matrices P, Q and R which are 10 x 20, 20 x 30 and 30 x 40 matrices respectively. What is the minimum number of multiplications required to multiply the three matrices?

18000
12000
24000
32000

Question 4: What will be the output of the following Python code?
A = [[1, 2, 3], [4, 5, 6], [7, 8, 9]] display [A[row][1] for row in (0, 1, 2)]

[7, 8, 9]
[4, 5, 6]
[2, 5, 8]
[1, 4, 7]
