Task: Answer the multiple choice question.
Question: Which drug exhibits a -1.575% 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 other words.
Options:
a: COC(=O)[C@@H]1C[C@H]1[C@@H](NC(=O)c1cc(C)on1)c1ccccc1
b: Cc1ccc(C)c(NC(=S)NNC(=O)c2ccc(Br)o2)c1
c: COCCn1c(=S)[nH]c2cc(C(=O)N3CCN(Cc4ccc5c(c4)OCO5)CC3)ccc2c1=O
d: O=C(CCCCCN1C(=O)CCC1=O)Nc1ncn[nH]1
Answer: a. COC(=O)[C@@H]1C[C@H]1[C@@H](NC(=O)c1cc(C)on1)c1ccccc1
