Task: Answer the multiple-choice question.
Query: Which drug exhibits a -37.755% hERG inhibition at a concentration of 10uM?
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)c1scc(-c2ccc(Cl)cc2)c1C#N
b. C[n+]1c(-c2ccccc2)sc2ccccc21.[O-][Cl+3]([O-])([O-])[O-]
c. N#Cc1cc(C(=O)c2cc(Br)ccc2O)cn(C2CCCCC2)c1=O
d. CCOc1cc(C)nc(N2CCN(C3CCCCC3)CC2)n1
e. CCn1c(=O)c2sccc2n(CC(=O)NCCC2=CCCCC2)c1=O
Answer: a. CCS(=O)c1scc(-c2ccc(Cl)cc2)c1C#N
