The correct answer is 'ARE'. When multiple subjects are joined by 'and', they form a COMPOUND SUBJECT and take a plural verb. Example: 'Reading and writing are important skills.' Three activities (noise making, bullying, smoking) are mentioned, so we need the plural verb 'are'. This is different from when 'and' joins words that form a single idea, like 'bread and butter is my favorite'.
