Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 5.112\% 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.) COc1ccccc1OCc1ccc(C(=O)NN)cc1
b.) CCCCOc1ccc2ccccc2c1C=O
c.) COc1cc(-c2nnc(COC(=O)c3cc(C)nc4ccc(C)cc34)o2)cc(OC)c1OC
d.) O=C(Nc1ccc(F)cc1F)N1CCCCCC1
Answer: a. COc1ccccc1OCc1ccc(C(=O)NN)cc1
