Task: Answer the multiple-choice question.
Question: Which drug has a 3.674\% 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) O=C1CCCC(=O)N1c1ccc(O)cc1
(b) CN(CC(=O)NCCc1ccccn1)S(=O)(=O)c1ccc(Cl)cc1
(c) CC(=O)c1cc2c(cc1NC(=O)CCCC(=O)O)OCO2
(d) Cn1[nH]c(-c2ccccc2)c(/C=N/O)c1=O
Answer: a. O=C1CCCC(=O)N1c1ccc(O)cc1
