Task: Answer the multiple choice question.
Query: Which drug exhibits a 4.535\% 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 additional words.
Options:
a COc1cccc(CNCCSc2nnnn2C)c1OC.Cl
b O=C(NC1CCCC1)c1ccc(CS(=O)(=O)c2ccc(Br)cc2)o1
c O=C(NCc1ccccc1CN1CCCC1)c1cccc(S(=O)(=O)Nc2ccc(F)cc2)c1
d O=C(NC1CCCc2c1cnn2-c1ccc(F)cc1F)c1ccccc1N1CCOCC1
Answer: a. COc1cccc(CNCCSc2nnnn2C)c1OC.Cl
