Task: Answer the MCQ question.
Question: Which drug exhibits a -2.692\% 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 additional words.
Options:
a.) CC(C)C(=O)NC(=S)Nc1ccc(S(=O)(=O)Nc2ccccc2)cc1
b.) Cc1ccc(S(=O)(=O)N(C)C)cc1NC(=O)COC(=O)CCC(=O)c1ccc(F)cc1
c.) CC(=O)N1CCC(C(=O)Nc2ccc(S(=O)(=O)N3CCCCC3)cc2)CC1
d.) CCCNC(=O)/C=C/C(=O)O
e.) CN(C)S(=O)(=O)c1cccc(NC(=O)COC(=O)c2c[nH]c(=O)[nH]c2=O)c1
Answer: d. CCCNC(=O)/C=C/C(=O)O
