Task: Answer the multiple choice question.
Query: Which compound has a 18.675% 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 additional words.
Options:
a O=P(O)(CP(=O)(c1ccccc1)c1ccccc1)c1ccccc1O
b CCOC(=O)c1cnc2ccc(OCC)cc2c1NCc1cccnc1.Cl
c COc1cc(C(=O)NCC(=O)NNC(=O)C2COc3ccccc3O2)cc(OC)c1OC
d O=C(Nc1ccc(Cl)cc1)N1CCCN(Cc2ccccc2)C1
e Cc1nn(Cc2ccccc2)c(C)c1NC(=O)CSc1n[nH]c(C)c1[N+](=O)[O-]
Answer: a. O=P(O)(CP(=O)(c1ccccc1)c1ccccc1)c1ccccc1O
