Task: Answer the multiple-choice question.
Question: Which compound exhibits a 6.746\% 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 other words.
Options:
a: O=C(Nc1ccc(Br)cn1)c1ccc2ccccc2c1
b: Cn1c(N)c(C(=O)Nc2ccc(-c3ccccc3)cc2)sc1=S
c: COC(=O)c1ccc(NC(=O)COc2ccc(C3C(C#N)=C(N)Oc4c3ccc3ccccc43)cc2OC)cc1
d: Cc1c(NC(=O)c2ccc(S(=O)(=O)N(C)c3ccccc3)cc2)c(=O)n(-c2ccccc2)n1C
Answer: c. COC(=O)c1ccc(NC(=O)COc2ccc(C3C(C#N)=C(N)Oc4c3ccc3ccccc43)cc2OC)cc1
