Problem statement: Answer the multiple choice question.
Query: Which drug has a -6.766\% 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.) COc1ccc(/C=N/NC(=O)Cn2ccnc2C)cc1OC
b.) O=C(Nc1cnc2ccccc2c1)C1COc2ccccc2O1
c.) CC(/C=N/n1c(-c2ccccn2)n[nH]c1=S)=C\c1ccccc1
d.) Cc1nc(-n2nnc3cc(C)c(C)cc32)c2c3c(sc2n1)CCCC3
Answer: b. O=C(Nc1cnc2ccccc2c1)C1COc2ccccc2O1
