Task: Answer the multiple choice question.
Question: Which compound exhibits a 3.581\% 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 CSC1=NSC2=NC(=O)/C(=C/c3coc4ccccc4c3=O)C(=N)N12
b CCOC(=O)c1ccc(N/C(=N\S(=O)(=O)c2ccccc2C)c2ccccc2)cc1
c CCOC(=O)C1CCCN(C(=O)c2ccccc2SCC)C1
d N#Cc1c(NC(=O)c2cc(-n3cnnc3)ccc2Cl)sc2c1CCCC2
Answer: a. CSC1=NSC2=NC(=O)/C(=C/c3coc4ccccc4c3=O)C(=N)N12
