Task: Answer the multiple-choice question.
Query: Which drug exhibits a 13.108\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a. CCOc1cc(CNc2ncc(-c3ccc(OC)cc3)n2C)ccc1O.O=C(O)C(=O)O
b. O=C(c1ccc(Oc2ccccc2)cc1)c1nc2c(n1O)CCCC2
c. CCCC1O[C@@H]2C[C@H]3[C@@H]4CCC5=CC(=O)C=C[C@]5(C)[C@H]4[C@@H](O)C[C@]3(C)[C@]2(C(=O)CO)O1
Answer: b. O=C(c1ccc(Oc2ccccc2)cc1)c1nc2c(n1O)CCCC2
