Answer:
B). To encourage readers to look for birds.
Explanation:
As per the given sentence, the idea of proposing different ways to own a 'Big Year' is 'to encourage the readers to look for birds'. The author's central idea is that he wishes the readers to explore the birds and have a birding experience. He feels that to have a 'big year', it does not require 'a travel to a big birding continent' or 'winning of cash prizes' but only requires to 'explore the as many possible distinct species of birds'. Therefore, he convinces and motivates the readers to 'look for the birds and their distinct species' to have a 'big year' instead of insignificantly involving in a competition of prizes and beating each other. Hence, option B is the correct answer.
