Task: Answer the multiple-choice question.
Query: Which drug exhibits a 13.130\% 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=C1N(Cc2cccnc2)C[C@@H]2C[C@@H](c3cccc(OC4CCCC4)c3)N3CCC[C@@]123
b. CN1CCN(C2=NCCO2)CC1
c. O=C(NCc1ccccc1Cl)C1CCCN1C(=O)NC1CCCCC1
d. N#C/C(=N\O)c1nc(-c2ccccc2)cs1
Answer: c. O=C(NCc1ccccc1Cl)C1CCCN1C(=O)NC1CCCCC1
