Problem statement: Answer the multiple choice question.
Query: Which drug has a 9.065\% 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=c1c2ccccc2cnn1-c1ccc(Br)cc1
b) O=C(NCC1CCCCC1)c1cccnc1Cl
c) CCc1nnc(NC(=O)C2=NN(C3CCS(=O)(=O)C3)C(=O)CC2)s1
Answer: a. O=c1c2ccccc2cnn1-c1ccc(Br)cc1
