To find the probability that the Lions will score less than 3 goals, we need to add the probabilities of scoring 0, 1, or 2 goals.

P(X < 3) = P(X = 0) + P(X = 1) + P(X = 2) 
P(X < 3) = 0.05 + 0.25 + 0.25 
P(X < 3) = 0.55

Therefore, the probability that the Lions will score less than 3 goals is 0.55. The best choice is B.
