Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 2.772\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
(a) CCOC(=O)CC1C(=O)NCCN1C(=O)c1c(F)cccc1F
(b) C/C(=N\Nc1ccccc1[N+](=O)[O-])c1ccccc1O
(c) Cc1sc2nc(CC(=O)N3CCCC3)[nH]c(=O)c2c1C
(d) CC1(C)CC(=O)C(C=NC(CCC(N)=O)C(=O)O)=C(O)C1
(e) COc1ccc(/C=C(\C#N)C(=O)OCC(=O)Nc2c(C)cccc2C(C)C)cc1
Answer: c. Cc1sc2nc(CC(=O)N3CCCC3)[nH]c(=O)c2c1C
