Direct connect supports jumbo frames: https://aws.amazon.com/about-aws/whats-new/2018/10/aws-direct-connect-now-supports-jumbo-frames-for-amazon-virtual-private-cloud-traffic/ Dunno about VPN but since it travels on the Internet I would say No.

Direct Connect could support Jumbo frames. But when talking about VPN, if it's specified, it's always through Internet, so MTU 1500 is supported by all the Internet parties. MTU 1500 meets both requirements. Answer is A
