Task: Answer the multiple choice question.
Question: Which compound has a 5.047\% 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)c1oc2cc(O)c(CC)cc2c(=O)c1-c1cscn1
b) O=C(N/N=C/C1CC2CCC1C2)c1c[nH]c2ccccc12
c) COc1cc(CC(=O)Nc2ccccc2N2CCCCC2)cc(OC)c1OC
d) CCOC(=O)c1ccc(CNC(=O)C(Cc2c[nH]c3ccccc23)NC(C)=O)o1
Answer: b. O=C(N/N=C/C1CC2CCC1C2)c1c[nH]c2ccccc12
