Task: Answer the multiple choice question.
Query: Which drug exhibits a -2.702\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a COCCn1c(SCC(=O)N2CCc3ccccc32)nc2c(c1=O)SC(C)C2
b COc1ccc(-n2nnc3c(=O)n(CC(=O)OCc4ccccc4)cnc32)cc1
c CCOc1cc(C(=O)NC)cc(Br)c1OC
d C=CCNC(=O)C1=NN(c2c(F)c(F)cc(F)c2F)C(=O)CC1
Answer: a. COCCn1c(SCC(=O)N2CCc3ccccc32)nc2c(c1=O)SC(C)C2
