Problem statement: Answer the multiple-choice question.
Question: Which drug has a 8.943\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a) O=c1[nH]c(=O)n(-c2ccc(Br)cc2)c(O)c1C=NC(CO)(CO)CO
b) CC1(C)CSC(=NCCc2ccccc2)N1C(=O)c1ccc(C#N)cc1
Answer: a. O=c1[nH]c(=O)n(-c2ccc(Br)cc2)c(O)c1C=NC(CO)(CO)CO
