Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 4.760\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a COc1cc(/C=N/NC(=O)c2csc3c2CCCC3)ccc1OCCN1CCOCC1
b Cc1ccc(C)c(NC(=O)C(Sc2cccc[n+]2[O-])c2ccccc2)c1
c O=C(c1ccccc1)c1nccc2ccccc12
d COc1ccc(NC(=O)NNC(=O)COc2cc(C)c(Cl)c(C)c2)c(OC)c1
e COc1ccccc1NC(=O)CN1C(=O)COc2ccc(S(=O)(=O)N3CCCCCC3)cc21
Answer: c. O=C(c1ccccc1)c1nccc2ccccc12
