Task: Answer the multiple choice question.
Question: Which drug has a 7.123\% 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] CC(NC(=O)CCCOc1ccc(Cl)cc1)c1ccccc1
[b] O=C(NCCCN1CCN(CCCNC(=O)c2cc([N+](=O)[O-])ccc2Cl)CC1)c1cc([N+](=O)[O-])ccc1Cl
[c] COc1ccc(COc2ccc3c(C)cc(=O)oc3c2)cc1
[d] N#Cc1cc2c(nc1SCC(O)CS(=O)(=O)Cc1ccc(Cl)cc1)CCCC2
Answer: c. COc1ccc(COc2ccc3c(C)cc(=O)oc3c2)cc1
