Task: Answer the multiple-choice question.
Question: Which drug exhibits a 8.851\% 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. NC(=O)N/N=C\c1cccs1
b. O=C(c1cc(-c2ccc(Cl)cc2)n(-c2ccc(Cl)c(Cl)c2)n1)N1CCOCC1
c. Cc1ccc(C(=O)Nc2c3c(nn2C(C)(C)C)CS(=O)(=O)C3)cc1C
d. CC(CCc1ccco1)NC(=O)Nc1cccc(F)c1
Answer: a. NC(=O)N/N=C\c1cccs1
