Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 23.294\% 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. Cc1ccc2nc(NS(C)(=O)=O)sc2c1
b. COc1ccc(-n2cnnc2SCC(=O)Nc2cccc(S(N)(=O)=O)c2)cc1
c. COc1ccc(CCNC(=O)Nc2cc(F)c(F)cc2Cl)cc1OC
d. Cc1ccc(N/C=C(/C#N)c2ccsc2)cc1C
Answer: c. COc1ccc(CCNC(=O)Nc2cc(F)c(F)cc2Cl)cc1OC
