Task: Answer the multiple choice question.
Query: Which drug exhibits a 10.891\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
(a) COc1ccc2cc(C(=O)O)n(CC(=O)c3ccccc3)c2c1
(b) O=C(NNC(=S)NC(=O)c1ccc(Br)cc1)c1ccc([N+](=O)[O-])cc1
(c) COc1ccc(CN2CCNC(=O)C2CC(=O)N(C)CC2CCOCC2)cc1OC
(d) C=CCNc1ncnc2c1cnn2-c1cccc(C)c1
Answer: a. COc1ccc2cc(C(=O)O)n(CC(=O)c3ccccc3)c2c1
