Task: Answer the multiple choice question.
Query: Which drug exhibits a -2.470% 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)N(C)c1nc2ccccc2s1
[b] CCOC(=O)Nc1cccc(C(=O)O)c1
[c] OCCN1C[C@H](O)[C@@H](O)[C@H](O)[C@H]1CO
[d] Cc1cccc(-n2c(N)c(-c3nc4ccccc4n3C)c3nc4ccccc4nc32)c1
Answer: c. OCCN1C[C@H](O)[C@@H](O)[C@H](O)[C@H]1CO
