Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a -0.023\% 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. CCOc1ccc2c(=O)c(Oc3ccccc3OCC)coc2c1
b. Cc1ccc2[nH]c(=O)c(CN(CCCN3CCOCC3)C(=O)NC3CCCCC3)cc2c1
c. COc1ccc(-n2nc(C(=O)NCC(=O)NC3CCCC(C)C3C)c3ccccc3c2=O)c(OC)c1
d. COc1cc(/C=C2\C(=N)N3N=C(S(C)(=O)=O)SC3=NC2=O)ccc1OS(=O)(=O)c1ccccc1
Answer: a. CCOc1ccc2c(=O)c(Oc3ccccc3OCC)coc2c1
