Problem statement: Answer the multiple-choice question.
Question: Which compound exhibits a 5.258\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
(a) C=CCCN([C@@H](C)C(=O)OC)S(=O)(=O)c1ccccc1Br
(b) COc1ccc(-c2nnc(SCC(=O)Nc3ccc(Cl)cc3)n2C)cc1
(c) CN(C)CCOC(=O)/C(=C/c1cn(C)c2ccccc12)NC(=O)c1ccccc1
(d) CC1(C)Cc2c(cnn2-c2ccccc2)-c2c1c1ccccc1n2CC(O)CBr
(e) COc1ccccc1-n1c(O)c(/C=C2\C=Nc3ccccc32)c(=O)[nH]c1=O
Answer: a. C=CCCN([C@@H](C)C(=O)OC)S(=O)(=O)c1ccccc1Br
