Jane has been operating Mansfield Park as a C corporation and decides she would like to make an S election. What is the earliest the election will become effective under each of these alternative scenarios?
a. Jane is on top of things and makes the election on January 1, 2018. 

b. Jane is mostly on top of things and makes the election on January 15, 2018.
c. Jane makes the election on February 10, 2018. She needed a little time to convince a C corporation shareholder to sell its stock to a qualifying shareholder. That process took all of January, and she was glad to have it over with.
d. Jane makes the election on March 14, 2018.
e. Jane makes the election on February 5, 2018. One of the shareholders refused to consent to the S election. He has since sold his shares (on January 15, 2018) to another shareholder who consented to the election.
