Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 2.564\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
[a] CCCCn1c(SCC(=O)N2CCCCC2C)nc2cc(S(N)(=O)=O)ccc21
[b] C=CCn1c(SCC(=O)N(C)C2CCS(=O)(=O)C2)nnc1-c1ccncc1
Answer: a. CCCCn1c(SCC(=O)N2CCCCC2C)nc2cc(S(N)(=O)=O)ccc21
