Task: Answer the multiple choice question.
Query: Which drug exhibits a 2.847\% 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) COc1cc(C(=O)NCC(=O)NCCCSc2ccccc2)cc(OC)c1OC
(b) CC(=O)NC1C(=O)N(CCN2CCOCC2)c2ccc(C)cc21
(c) CC(=O)c1cc(F)c(N2CCN(C(=O)c3ccco3)CC2)cc1C
(d) CCc1ccc2c(CN3CC=C(c4ccccc4)CC3)cc(=O)oc2c1
(e) O=S(=O)(c1ccc(Br)cc1)N1CCN(c2ccccc2)CC1
Answer: d. CCc1ccc2c(CN3CC=C(c4ccccc4)CC3)cc(=O)oc2c1
