B. The person was first employed as a law enforcement officer at the Baxter State Park Authority before November 1, 1995, elects the option provided in section 17851, subsection 12 or 12-A and pays to the retirement system single or periodic payment of a lump sum or by a combination of single and periodic payments of the amount that equals the full actuarial cost of electing that option for service before that date.
