Dan developed a methodology for picking lottery numbers based on a mathematical equation that accounted for the probability of each number appearing based on how many times it appeared as a winning number in the past. Dan's method actually resulted in him winning several small jackpots. Dan has been asked to appear on a television show to discuss how he was able to correctly guess the winning lottery numbers multiple times. Is there a way for Dan to protect his methodology and still talk about it on television?

a. Dan can copyright his method.

b. Dan may be able to protect his method as a trade secret, but would not be able to discuss it on television.

c. Dan can trademark his method.

d. Dan can obtain a utility patent on his method which will prohibit others from using his method even if he discusses it on television.
