What is the output of following code ?

निम्नलिखित कोड का आउटपुट क्या है?

A=[[1,2,3],
[4,5,6],
[7,8,9]]
print(A[1][:])

[1, 2, 3]

[4, 5, 6]

[2, 5, 8]

None of these

Explanation:

The correct answer is:

(B) [4, 5, 6]

A is a 2D list (a list of lists), where A[1] refers to the second list (since indexing starts from 0), which is [4, 5, 6].
The [:] slice operator is used to copy the entire list at index 1. So, A[1][:] gives the list [4, 5, 6].

(B) [4, 5, 6]
