Bob has a circannual rhythm of 11 months.

Explanation:

Circannual rhythm is derived from the Latin words 'circa' meaning approximately and 'annual' meaning 'a period of one year.' So, Circannual rhythm can be defined as a biological rhythm in loving beings that occurs annually. This rhythm happens even in the absence of environmental cues. The rhythm was developed by Ted Pengelley and Ebo Gwinner.

In the given case, the circannual rhythm of Bob, a tortoise, is of 11 months as he hibernated in the first year in October, then in September, and then in August.

So, the correct answer is circannual rhythm of 11 months.
