Task: Answer the multiple choice question.
Question: Which drug exhibits a 4.930\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
(a) CC(=O)c1ccc(N2CCN(C(=O)CCCn3c(=S)[nH]c4cc5c(cc4c3=O)OCO5)CC2)cc1
(b) COCC(C)N=C1NN=C(c2cc(C)n(Cc3ccccc3Cl)c2C)CS1
Answer: b. COCC(C)N=C1NN=C(c2cc(C)n(Cc3ccccc3Cl)c2C)CS1
