Task: Answer the multiple-choice question.
Query: Which drug exhibits a 12.565\% 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=C(NCCN1CCOCC1)c1cc(Br)ccc1Cl
[b] CC(C)CC(C(=O)Nc1cccc(O)c1)N1C(=O)c2ccccc2C1=O
[c] CC(C)CCN1CCN(CC(c2ccccc2)c2ccccc2)CC1CCO
[d] O=C(COC(=O)CC1CCCC1)Nc1cccc(F)c1
Answer: a. O=C(NCCN1CCOCC1)c1cc(Br)ccc1Cl
