Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 2.776\% 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. CCOC(=O)C(NC(C)=O)(Nc1ccc(S(=O)(=O)Nc2nccs2)cc1)C(F)(F)F
b. Cc1ccnc2c(N3C(=O)C4C5C=CC(C5)C4(C)C3=O)cccc12
c. O=S1(=O)CCN2C=Nc3sc4c(c3C2=N1)CCCC4
d. O=C(Cn1nnc(-c2ccccc2)n1)OCc1csc(-c2ccccc2)n1
Answer: d. O=C(Cn1nnc(-c2ccccc2)n1)OCc1csc(-c2ccccc2)n1
