Task: Answer the multiple choice question.
Question: Which drug exhibits a 14.223\% human ether-à-go-go related gene (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 other words.
Options:
a O=C(NC(=S)NC1CCSC1=O)c1cccs1
b NC(=O)C1CCN(Cc2cccc(OCc3ccccc3)c2)CC1.O=C(O)C(=O)O
c CCCc1cc(CNC(=O)C2CCC(=O)N(Cc3ccccc3OC)C2)on1
d COc1ccc2oc(C(=O)NCc3ccco3)c(C)c2c1
Answer: a. O=C(NC(=S)NC1CCSC1=O)c1cccs1
