Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a -6.392\% 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 CCS(=O)(=O)N1CCC(C(=O)NCCc2ccccc2)CC1
b CCc1cccc(NC(=O)COc2ccccc2)c1
c COC(=O)c1cc(NC(=O)c2cccc(C(F)(F)F)c2)c(=O)oc1C/C=N/OCc1cccc(Cl)c1Cl
d C=CCNC(=O)CN(c1cccc(Br)c1)S(C)(=O)=O
e COc1ccc(OC)c(C2CC(=O)N3CN(c4ccccc4)CSC3=C2C#N)c1
Answer: d. C=CCNC(=O)CN(c1cccc(Br)c1)S(C)(=O)=O
