Selected Answer: D
List Definition: myli = [1, 2, 4] Mapping with Lambda Function: m = list(map(lambda x: 2**x, myli)) This applies the lambda function lambda x: 2**x to each element in myli. For x = 1, 2**1 = 2 For x = 2, 2**2 = 4 For x = 4, 2**4 = 16 So, m becomes [2, 4, 16]. Accessing the Last Element: print(m[-1]) prints the last element of the list m, which is 16.
