Task: Answer the multiple choice question.
Question: Which compound has a 0.175\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
(a) C/C=C/c1ccc(OCCCNCC(C)O)c(OC)c1
(b) Cc1ccc(C)c(NC(=O)CSc2nnc(-c3ccccc3C)o2)c1
(c) CCOC(=O)c1ccc(-n2c(-c3ccco3)nc3ccccc3c2=O)cc1
(d) COC(=O)C1=C(NC(=O)c2ccccc2[N+](=O)[O-])CCS1
Answer: a. C/C=C/c1ccc(OCCCNCC(C)O)c(OC)c1
