Task: Answer the multiple choice question.
Question: Which drug exhibits a 3.738\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
(a) O=S1(=O)N=C(Nc2nc3c(s2)CCCC3)c2ccccc21
(b) COCC(C)N=C1NN=C(c2cc(C)n(Cc3ccccc3Cl)c2C)CS1
(c) COc1cccc(C(=O)N2c3ccccc3Sc3ccccc32)c1
Answer: a. O=S1(=O)N=C(Nc2nc3c(s2)CCCC3)c2ccccc21
