Correct Answer: B
Explanation
VARA is a modern, proprietary digital protocol that is widely used in the amateur radio service for sending and receiving data and email. It is frequently employed as the high-speed modem protocol for the Winlink amateur radio email system.
VARA is an improvement over older protocols like PACTOR, offering higher data throughput and better performance under poor propagation conditions. Its high-speed capability has made it a popular choice for emergency communications and general file transfer over HF and VHF/UHF radio links, especially for users relying on Winlink.
