Problem statement: Answer the multiple choice question.
Query: Which compound exhibits a 14.648\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a.) COc1ccc(NC(C)=O)cc1CNC(=O)CN1CCOCC1
b.) N#Cc1c(NC(=O)COC(=O)C2CC3C=CC2C3)oc(-c2ccccc2)c1-c1ccccc1
c.) O=C(c1ccncc1)N1CCN(C(=O)c2ccncc2)CC1
Answer: c. O=C(c1ccncc1)N1CCN(C(=O)c2ccncc2)CC1
