Problem statement: Answer the multiple choice question.
Query: Which drug has a 7.838\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a. O=C(CCc1nnc(-c2ccc3c(c2)OCO3)o1)NCCc1ccccc1F
b. C=CCNC(=O)CN(c1cc(Cl)ccc1OC)S(=O)(=O)c1ccc(C)c([N+](=O)[O-])c1
c. CCOc1cccc2sc(N(CCN(C)C)C(=O)c3ccc4ccccc4c3)nc12.Cl
d. CC(C)NCCCCOc1ccc(Br)cc1Cl.O=C(O)C(=O)O
Answer: b. C=CCNC(=O)CN(c1cc(Cl)ccc1OC)S(=O)(=O)c1ccc(C)c([N+](=O)[O-])c1
