In Jainism, Vasudeva is a title used for a great heroic figure, and in the current time cycle, Lord Krishna is considered the ninth Vasudeva. According to Jain texts, the principal wife of Vasudeva Krishna is Rukmini.

The third letter of "Rukmini" is "k". If you are referring to another Vasudeva or a specific wife whose name's third letter is "bha", please provide more details. In Jain scriptures, the commonly mentioned wives of Vasudevas do not typically have "bha" as the third letter in their names.

If you have a specific context or a different Vasudeva in mind, kindly clarify, and I will do my best to assist you with Jain references.
