Task: Answer the multiple choice question.
Query: Which drug has a 2.338\% 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 additional words.
Options:
a: Cc1ccc(NC(=O)c2cc(C)n(-c3cccc(C)c3)c2C)cc1
b: COc1cc(CNC(=O)CCCC/C=C/C(C)C)ccc1O
c: O=C(Nc1ccc([N+](=O)[O-])cc1)/C(=C/c1cccc([N+](=O)[O-])c1)NC(=O)C1CCCCC1
d: N#CC1=C2SCC(O)(c3ccccc3)N2C(=O)CC1c1ccccc1
Answer: d. N#CC1=C2SCC(O)(c3ccccc3)N2C(=O)CC1c1ccccc1
