Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a -21.989\% 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.) CC(C)N1C(=O)C2C(C(=O)NC3CCCCC3)C3C=CC2(O3)C1C(=O)NC1CCCC1
b.) CN1CCN(CCCNc2c(C=O)c(=O)[nH]c3ccccc23)CC1
c.) CCOC(=O)c1c(C)[nH]c(C)c1S(=O)(=O)N(C)CC(=O)Nc1ccc(C)cn1
d.) Brc1ccc(CN2CCN(Cc3c[nH]c4ccccc34)CC2)cc1.O=C(O)C(=O)O
Answer: d. Brc1ccc(CN2CCN(Cc3c[nH]c4ccccc34)CC2)cc1.O=C(O)C(=O)O
