Problem statement: Answer the multiple-choice question.
Question: Which drug has a 15.015\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a. N#CC1=C(N)n2c(s/c(=C\c3ccco3)c2=O)=C(C#N)C1c1ccco1
b. Cc1nnc(SCc2nnc(-c3cccs3)o2)n1C
c. CC1CC(C)CN(S(=O)(=O)c2ccc3oc(=O)ccc3c2)C1
d. COc1ccc2[nH]c3c(=O)n(CCCN4CCOCC4)cnc3c2c1
e. O=C(/C=C/c1ccc(Cl)c([N+](=O)[O-])c1)NCc1cccnc1
Answer: b. Cc1nnc(SCc2nnc(-c3cccs3)o2)n1C
