Task: Answer the multiple choice question.
Query: Which drug exhibits a 4.862% 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=C(NCC1CCCO1)C1CCN(C2CCN(C(=O)CC3CCCC3)CC2)CC1
[b] COc1ccc(N(C)S(=O)(=O)c2cccc(C(=O)Nc3nc4ccccc4[nH]3)c2)cc1
[c] O=C(NCc1ccncc1)C(=O)NCC1OCCCN1S(=O)(=O)c1cc(F)ccc1F
[d] CCCOc1ccc(OCCOCCNCc2ccccc2)cc1.O=C(O)C(=O)O
Answer: c. O=C(NCc1ccncc1)C(=O)NCC1OCCCN1S(=O)(=O)c1cc(F)ccc1F
