Task: Answer the multiple choice question.
Question: Which drug exhibits a -7.000\% 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 additional words.
Options:
a. O=C(NCCNc1ccc([N+](=O)[O-])cc1)c1ccc(Cl)cc1
b. CCn1c(=O)cc(NC2=NCC(C)CN2c2cccc(Cl)c2)n(C)c1=O
c. CC1(C)SC[C@H](C(=O)Nc2cccc(Cl)c2)N1C=O
d. COc1ccc(-c2nc(CN3CCC(C(=O)NCC4CCCO4)CC3)c(C)o2)cc1OC
e. O=C(c1ccc2c(c1)CCN2S(=O)(=O)c1ccccc1)N1CCN(c2ccccc2)CC1
Answer: b. CCn1c(=O)cc(NC2=NCC(C)CN2c2cccc(Cl)c2)n(C)c1=O
