Task: Answer the multiple choice question.
Question: Which drug exhibits a -19.569% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
(a) O=c1c2ccccc2nc2n1C(CSc1ccccc1)CS2
(b) O=C(c1ccccc1F)N1CCN(CC2CC3C=CC2C3)CC1
(c) COc1ccc(OC(=O)CCc2c[nH]c3ccccc23)cc1
(d) CCc1cccc(NC(=S)N2CCC(c3ccccc3)C2)c1
Answer: a. O=c1c2ccccc2nc2n1C(CSc1ccccc1)CS2
