Explanation:

Step1: Identify E

E is a list containing sub - lists A, B, C.

Step2: Locate E[2]

In Python, list indices start from 0. So E[2] refers to the third sub - list in E, which is C = [12, 'fish', 'green'].

Step3: Locate E[2][1]

In the list C, the index 1 refers to the second element. So E[2][1] is 'fish'.

Answer:

fish
