Selected Answer: D
List Comprehension: my_list = [i for i in range(5)] This creates a list of integers from 0 to 4: [0, 1, 2, 3, 4]. Filtered List Comprehension: m = [my_list[i] for i in range(5) if my_list[i] % 2 != 0] This iterates over the indices 0 to 4 and includes my_list[i] in the new list m only if my_list[i] % 2 != 0 (i.e., the element is odd). The odd elements in my_list are 1 and 3. Output: print(m) prints the list m, which contains the odd elements [1, 3]
