Task: Answer the multiple choice question.
Question: Which drug exhibits a 14.645\% 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) COc1cc(-c2cc(-c3ccc(N)cc3)[nH]c(=O)c2C#N)cc(OC)c1OC
(b) COCCCn1c(=O)c2sccc2n2c(CCCC(=O)N(C)Cc3ccco3)nnc12
(c) C/C(N)=C(/C#N)C(=O)CN1CCCCC1
(d) CCc1c(C(=O)Nc2cc(C(=O)OC)ccc2C)csc1C
Answer: a. COc1cc(-c2cc(-c3ccc(N)cc3)[nH]c(=O)c2C#N)cc(OC)c1OC
