• A. It so happened that out of the blue, all the bears used to hold swimming competitions at the lake.
• B. It so happened that once in a blue moon, all the bears used to hold swimming competitions at the lake.

Answer 1

The correct option is B It so happened that once in a blue moon, all the bears used to hold swimming competitions at the lake.

The idiom ‘once in a blue moon’ is used to convey that something happens very rarely whereas ‘out of the blue’ is used to convey suddenness. Hence, the correct answer is ‘It so happened that once in a blue moon, all the bears used to hold swimming competitions at the lake’.
