Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a -2.506\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
[a] CCn1ccnc1CNCc1ccc(OCC(O)CN(C)Cc2ccccc2)cc1
[b] CCO[C@H]1OC(C(=O)Nc2ccccc2)=C[C@@H](c2coc3ccccc3c2=O)[C@@H]1CCCO
Answer: a. CCn1ccnc1CNCc1ccc(OCC(O)CN(C)Cc2ccccc2)cc1
