Problem statement: Answer the MCQ question.
Question: Which drug exhibits a -0.025\% 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. O=C(Nc1ccc(-c2csnn2)cc1)C1CC1
b. Cc1cccc(OCCCC(=O)Nc2ccc3c(c2)OCO3)c1
c. CC(C(=O)O)C(=O)O
d. O=c1[nH]c(=S)n(CCC2=CCCCC2)c(O)c1/C=N/N1CCOCC1
Answer: d. O=c1[nH]c(=S)n(CCC2=CCCCC2)c(O)c1/C=N/N1CCOCC1
