Task: Answer the multiple-choice question.
Question: Which drug has a 9.969\% 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 other words.
Options:
a. O=C1C=C(c2cc(F)ccc2F)C[C@@H](c2ccc(Cl)cc2)C1
b. O=C1N(Nc2ccccc2)C(c2ccc(Br)cc2)C12CCCCC2
c. Nc1cc(C(=O)O)c(N)c2c1C(=O)c1ccccc1C2=O
d. O=C(O)C1Cc2ccccc2CN1C(=O)CSc1nnc2ccccn12
Answer: a. O=C1C=C(c2cc(F)ccc2F)C[C@@H](c2ccc(Cl)cc2)C1
