Task: Answer the multiple choice question.
Question: Which drug exhibits a -16.693% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
[a] COC(=O)c1cc(-c2c(C)oc3cc(OC(C)C)ccc3c2=O)c(C)o1
[b] CS(=O)CSc1nc2c(cc1C#N)CCCC2
[c] Cc1cccc(-n2nnnc2SCc2csc(-c3ccccc3)n2)c1
[d] O=C(O)c1cc2nc(-c3ccccc3)cc(-c3ccccc3)n2n1
Answer: a. COC(=O)c1cc(-c2c(C)oc3cc(OC(C)C)ccc3c2=O)c(C)o1
