Task: Answer the multiple choice question.
Query: Which compound exhibits a 18.057\% 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 additional words.
Options:
a. O=C1Nc2ccccc2C(O)(C(=O)NCc2ccc3c(c2)OCO3)N1c1ccc(Cl)c(Cl)c1
b. COc1cc(CN2CCCC(CO)(Cc3ccccc3)C2)ccc1O
c. COc1ccc(F)cc1S(=O)(=O)N1CCCCC1
d. O=C(COC(=O)c1ccc(Br)o1)Nc1ccc2[nH]c(=O)[nH]c2c1
Answer: a. O=C1Nc2ccccc2C(O)(C(=O)NCc2ccc3c(c2)OCO3)N1c1ccc(Cl)c(Cl)c1
