Task: Answer the multiple choice question.
Question: Which drug exhibits a 2.089\% 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 Cc1cc(C)c2nc(SC(C)C#N)cc(C)c2c1
b S=C(NCCc1ccccc1)NCC(c1ccco1)N1CCCCC1
c Cc1c(NC(=O)/C(C#N)=C/c2ccc(-c3cccc(Cl)c3)o2)c(=O)n(-c2ccccc2)n1C
d CC(=O)SC(C)CC(=O)Nc1ccccc1
Answer: c. Cc1c(NC(=O)/C(C#N)=C/c2ccc(-c3cccc(Cl)c3)o2)c(=O)n(-c2ccccc2)n1C
