Task: Answer the multiple choice question.
Question: Which drug has a 4.474\% 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, or c without using any other words.
Options:
(a) Cn1c(=O)[nH]c(=O)c2c1nc(SCC(N)=O)n2Cc1cccc(Br)c1
(b) O=[N+]([O-])c1ccccc1/C=C/C=N/N1CCCCC1
(c) CCC1CCCCN1CCCNC(=O)c1ccc2c(=O)n(Cc3ccc(OC)cc3)c(=O)[nH]c2c1
Answer: a. Cn1c(=O)[nH]c(=O)c2c1nc(SCC(N)=O)n2Cc1cccc(Br)c1
