Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a -0.575\% 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 or b without using any additional words.
Options:
a CC1CCN(S(=O)(=O)c2ccc3c(c2)N(CC(=O)NCCCN2CCCCC2)C(=O)CS3)CC1
b O=C1Nc2ccc(Br)cc2/C1=C/C1CC=CCC1
Answer: b. O=C1Nc2ccc(Br)cc2/C1=C/C1CC=CCC1
