Task: Answer the multiple choice question.
Query: Which compound exhibits a 18.635\% human ether-à-go-go related gene (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.) CCOC(=O)C1CCN(S(=O)(=O)c2ccc3c(c2)N(C(C)=O)CC(C)S3)CC1
b.) COc1cccc(OCC(O)CN2CCN(c3ccccn3)CC2)c1.Cl
c.) Cc1ccc2cc(CCNC(=O)c3ccc4c(c3)OCO4)c(=O)[nH]c2c1
d.) COCCCn1c(=O)c2sccc2n2c(CCCC(=O)NCc3ccc(OC)cc3)nnc12
e.) CCn1c(=O)cc(C(F)(F)F)[nH]c1=S
Answer: e. CCn1c(=O)cc(C(F)(F)F)[nH]c1=S
