Task: Answer the multiple choice question.
Question: Which drug exhibits a 19.484% 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 COc1cc2c(C#CCCO)c(-c3ccc(C#N)cc3)oc(=O)c2cc1OC
b CCCCCn1c(SCC2CCCO2)nc2cc(C(=O)N3CCC(C(N)=O)CC3)ccc2c1=O
c COc1cc(NC(=O)C2CCN(c3cnccn3)CC2)cc(OC)c1OC
d CCC(=O)N1CCc2cc(Br)cc(S(=O)(=O)N3CCN(C(=O)c4ccco4)CC3)c21
Answer: c. COc1cc(NC(=O)C2CCN(c3cnccn3)CC2)cc(OC)c1OC
