Task: Answer the multiple-choice question.
Query: Which drug has a 13.963\% 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. O=C(Cc1n[nH]c(=O)c2ccccc12)OCC(=O)c1ccccc1
b. O=C(CCNS(=O)(=O)c1ccccc1)N1CCN(c2ccccc2)CC1
c. CCN(Cc1cccs1)C(=O)CN1C(=O)NC2(CCCc3ccccc32)C1=O
Answer: a. O=C(Cc1n[nH]c(=O)c2ccccc12)OCC(=O)c1ccccc1
