.b. The program would display the list [1, 2, 3, 4]

Explanation:

list ← [ 1, 2, 3 ]: this would create a list of [1, 2, 3]

APPEND ( list, 5 ): this would append 5 to the existing list and the output would be [1, 2, 3, 4, 5]

INSERT ( list, 4, 4 ): this would insert 4 at index 4 of the list and we would have the list to be [1, 2, 3, 5, 4]. The list index counting is from zero.

REMOVE ( list, 5 ): this would remove the occurrence of 5 from the list and the resulting list is [1, 2, 3, 4]

DISPLAY ( list ): this would display the list which is [1, 2, 3, 4]
