Task: Answer the multiple-choice question.
Question: Which drug exhibits a 15.675\% 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. COc1ccccc1N1C(=O)C2CC=CC(C)C2C1=O
b. CC1(c2ccc3ccccc3c2)NC(=O)N(CC(N)=O)C1=O
c. O=C(c1ccccc1)[C@H]1[C@H](c2ccccc2)[C@@]2(N=C(c3ccccc3)OC2=O)C2c3ccccc3C=NN21
d. COc1ccc(C(C(=O)NC(C)(C)C)N(C(=O)CCC(=O)Nc2cc(C)on2)c2cccc(C)c2C)cc1
Answer: c. O=C(c1ccccc1)[C@H]1[C@H](c2ccccc2)[C@@]2(N=C(c3ccccc3)OC2=O)C2c3ccccc3C=NN21
