Task: Answer the multiple choice question.
Question: Which drug exhibits a -6.041\% 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 other words.
Options:
a.) CCCCC(=O)Nc1ccc(NC(=O)c2ccccc2[N+](=O)[O-])cc1OC
b.) CC1CCCC(NC(=O)C2CCN(S(=O)(=O)N3CCCCCC3)CC2)C1C
c.) CN(CC(=O)Nc1ccccc1Cl)C(=O)COC(=O)c1ccc([N+](=O)[O-])cc1Cl
d.) O=C(c1c[nH]c2ccc(S(=O)(=O)N3CCC4(CC3)OCCO4)cc2c1=O)N1CCC2(CC1)OCCO2
Answer: a. CCCCC(=O)Nc1ccc(NC(=O)c2ccccc2[N+](=O)[O-])cc1OC
