Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 14.553\% 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 CCCN(CC1CC1)C(=O)COC(=O)c1oc2c(F)cccc2c1C
b O=C(NCc1ccc2c(c1)OCO2)c1ccc(Cl)c(S(=O)(=O)NCc2ccccc2)c1
c O=C(O)CCN1C(=O)C2C3C=CC(C3)C2C1=O
d CN1CCN(Cc2c(O)ccc3cc(Br)ccc23)CC1
Answer: c. O=C(O)CCN1C(=O)C2C3C=CC(C3)C2C1=O
