Task: Answer the multiple-choice question.
Question: Which drug exhibits a 21.595\% 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. CCOC(=O)/C(C#N)=C\c1ccco1
b. CC(C)Oc1nnnn1-c1ccccc1
c. Cc1[nH]n(-c2ccc(Cl)cc2)c(=O)c1/C=N/c1nnc(-c2ccccc2)s1
d. CCCCn1c(N)c(N(CC(C)C)C(=O)c2cccc(OCc3ccccc3)c2)c(=O)[nH]c1=O
Answer: c. Cc1[nH]n(-c2ccc(Cl)cc2)c(=O)c1/C=N/c1nnc(-c2ccccc2)s1
