Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a -5.821\% 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=C(N/N=C/c1cccnc1)c1ccc2c(c1)OCCO2
b COc1ccc(-c2nc(C)ncc2-c2ccc(Cl)cc2)c(O)c1
Answer: a. O=C(N/N=C/c1cccnc1)c1ccc2c(c1)OCCO2
