Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 0.392\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a.) O=c1c2nccnc2[nH]c(=S)n1Cc1ccccc1
b.) Cc1ccc(NC(=S)NC2CCN(Cc3ccccc3)CC2)cc1
c.) COc1cccc(/C=C2/C(=O)NN(c3ccc(F)cc3)C2=O)c1
d.) CCC1(C)Cc2ccccc2-c2[nH]c(=S)[nH]c(=O)c21
e.) O=C(NCCO)C1(c2ccc(Cl)cc2)CCCC1
Answer: a. O=c1c2nccnc2[nH]c(=S)n1Cc1ccccc1
