Task: Answer the multiple choice question.
Query: Which drug has a 5.978\% 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(Nc1cccc(NC(=O)c2cccs2)c1)c1ccc([N+](=O)[O-])o1
b CCOc1ccc(OCCOc2ccc(/C=C/C(=O)O)cc2OCC)cc1
c CN(CC(=O)NCCc1ccc(F)cc1)Cc1cccs1
d O=C(CCSc1nc2ccccc2o1)Nc1ccccc1
Answer: b. CCOc1ccc(OCCOc2ccc(/C=C/C(=O)O)cc2OCC)cc1
