Task: Answer the multiple-choice question.
Question: Which drug has a 13.560\% 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, or d without using any additional words.
Options:
(a) O=C(CSc1nc2sc3c(c2c(=O)n1-c1ccccc1)CCCC3)N/N=C/c1ccccc1C(=O)O
(b) Cn1c(NCCO)nc2c(c1=O)C1(CCCCC1)Cc1ccccc1-2
(c) O=C(CN1C(=O)/C(=C/c2ccccc2)SC1=S)NC1CCS(=O)(=O)C1
(d) COc1cccc(-n2nnnc2SCC(=O)NCCc2ccc(OC)c(OC)c2)c1
Answer: a. O=C(CSc1nc2sc3c(c2c(=O)n1-c1ccccc1)CCCC3)N/N=C/c1ccccc1C(=O)O
