(A) Lenin did not train as hard as Adam trained.
(B) If Adam trained hard, she would win the sailboat race.
(C) Adam could beat a four-time winner only if she trained hard.
(D) If Lenin trained hard, she would win the sailboat race.
(E) Lenin is usually a faster sailboat racer than Adam

Fact 1: Adam won the race beating Lenin.
Fact 2: Lenin is the winner in each of four years.
Conclusion: Adam trained hard.
Let's make few assumptions before checking the answer choices:
A1: There was no dip in Lenin performance and Adam's performance improved because of hard training.
A2: No other factor contributed to Adam's advantage such as, superior boat.
Let's look at the answer choices:
(A) Lenin did not train as hard as Adam trained: Incorrect. Even if Lenin trained as hard, he could have still lost the race.
(B) If Adam trained hard, she would win the sailboat race : Incorrect. This is one of the ways he can win the race but not the only way.
(C) Adam could beat a four-time winner only if she trained hard : Bingo!! This makes it a necessary condition.
(D) If Lenin trained hard, she would win the sailboat race : Incorrect. Nothing to do with Lenin's training.
(E) Lenin is usually a faster sailboat racer than Adam : Incorrect. Nothing to do with the conclusion.
Fact 2: Lenin is the winner in each of four years.
Conclusion: Adam trained hard.
