Task: Answer the multiple choice question.
Question: Which drug exhibits a 11.855\% 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] COC(=O)c1ccc(Oc2c(Cl)cccc2[N+](=O)[O-])cc1
[b] COc1cc(CNC(=O)CCCC/C=C/C(C)C)ccc1O
[c] COc1ccc(CCNC(=O)C2CCCN(Cc3nc(-c4ccccc4C)oc3C)C2)cc1OC
[d] CCc1c(C(=O)NCc2ccccc2Cl)[nH]c(C)c1C(C)=O
Answer: a. COC(=O)c1ccc(Oc2c(Cl)cccc2[N+](=O)[O-])cc1
