Task: Answer the multiple choice question.
Query: Which drug exhibits a -7.850% 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 other words.
Options:
a. CCOc1cccc(CNCCNC(=O)c2nonc2N)c1.Cl
b. CCN(CC(=O)Nc1c(F)cccc1F)C(=O)c1ccc(=O)n(Cc2ccccc2)n1
c. CCCNC(=O)c1onc(CSc2ccc(F)cc2)c1C(=O)NCC1CC1
d. COc1ccc(-n2c(O)c(C(C)=Nc3ccc4c(c3)CCC4)c(=O)[nH]c2=O)cc1
Answer: a. CCOc1cccc(CNCCNC(=O)c2nonc2N)c1.Cl
