Task: Answer the multiple choice question.
Question: Which drug exhibits a -0.550\% human ether-à-go-go related gene (hERG) inhibition at 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(NCCCN1CCCC1)c1ccc2c(c1)N(Cc1ccc(F)cc1)C(=O)c1ccccc1S2=O
b.) COc1ccc(C(=O)C[n+]2cccc(C)c2)cc1.[Br-]
c.) Cc1nc2ccc(C(=O)N(C)CC3CCCN(CCc4ccc(Cl)cc4)C3)cc2[nH]1
d.) CSc1ccc(CN(C)CC(=O)N(C)CC(=O)Nc2ccccc2Br)cc1
Answer: c. Cc1nc2ccc(C(=O)N(C)CC3CCCN(CCc4ccc(Cl)cc4)C3)cc2[nH]1
