Problem statement: Answer the multiple-choice question.
Query: Which drug exhibits a 6.992\% 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 additional words.
Options:
a. Cl.N=c1ccn(Cc2c(Cl)cccc2Cl)cc1
b. O=c1cc(-c2c(O)c3ccccc3n(Cc3ccccc3)c2=O)[nH][nH]1
c. C=CCN1CN(Cc2ccco2)CNC1=S
d. CN1CCN(Cc2ccccc2C(F)(F)F)CC1
Answer: b. O=c1cc(-c2c(O)c3ccccc3n(Cc3ccccc3)c2=O)[nH][nH]1
