Spot the bug in training code

What is wrong with this code?

X_train, X_test, y_train, y_test = train_test_split(X, y, test_size=0.2)
model = RandomForestClassifier()
model.fit(X_test, y_test)
print(model.score(X_test, y_test))

A.RandomForestClassifier has no score methodB.It trains on the test rows, so the score is meaninglessC.test_size must be an integer, not a fractionD.train_test_split must be given the labels first
