Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 5.441\% 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: Cc1ccc(C)c(N2CCN(C(=O)Cc3ccc(NC4=NC5CS(=O)(=O)CC5S4)cc3)CC2)c1
b: Cc1ccc(/C=N/NC(=O)CNC(=O)c2ccc(S(=O)(=O)N(C)C)cc2)o1
c: COC(C(=O)N/N=C(\C)c1ccc(O)cc1)c1ccccc1
d: COc1cccc(N2CC(NC(=O)C(=O)c3c[nH]c4ccccc34)CC2=O)c1
e: CS(=O)(=O)Nc1cccc(C2=NN(S(C)(=O)=O)C(c3ccc4c(c3)OCO4)C2)c1
Answer: c. COC(C(=O)N/N=C(\C)c1ccc(O)cc1)c1ccccc1
