Task: Answer the multiple choice question.
Question: Which drug has a 7.474\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a) CCCCn1nc(C(=O)NNC(=O)c2ccncc2)c2ccccc2c1=O
b) Cc1oc(-c2ccc(Cl)cc2)nc1CN1CCCC(C(=O)NCCCN2CCCC2=O)C1
c) Cc1ccc2nc(=O)c(NNc3ccccc3)cnc2c1
Answer: a. CCCCn1nc(C(=O)NNC(=O)c2ccncc2)c2ccccc2c1=O
