Task: Answer the multiple choice question.
Question: Which drug has a 7.893\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
(a) O=C(N=C1c2ccccc2CN1c1cccc(Cl)c1)c1cccnc1
(b) CCCCn1nc(C(=O)N(CCOC)c2c(N)n(CCCC)c(=O)[nH]c2=O)c2ccccc2c1=O
(c) O=C(OCC(=O)c1ccc(Cl)s1)c1ccc(CO)cc1
Answer: a. O=C(N=C1c2ccccc2CN1c1cccc(Cl)c1)c1cccnc1
