Task: Answer the multiple choice question.
Query: Which compound has a 2.576% 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, d, or e without using any other words.
Options:
a) COc1ccc(S(=O)(=O)Nc2ccccc2C(=O)NCc2cccnc2)cc1C
b) CCn1c(CNc2ccc(F)cc2)nnc1SCC(=O)OC1CCCCC1
c) O=C(Nc1cnccn1)Nc1ccccc1Cl
d) CSc1nc(N2CCN(Cc3ccc4c(c3)OCO4)CC2)c2ccccc2n1
e) N#Cc1ccccc1NC(=O)CC1CCCCC1
Answer: c. O=C(Nc1cnccn1)Nc1ccccc1Cl
