Task: Answer the multiple choice question.
Query: Which drug has a 1.977\% human ether-à-go-go related gene (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: C/C(=N\NC(=O)CCc1ccc(S(=O)(=O)N2CCOCC2)cc1)c1ccc(OC(F)F)cc1
b: CN(C(=S)SCc1ccccc1)C1CCS(=O)(=O)C1
c: CN1CCN(C(CNC(=O)C(=O)Nc2ccc3c(c2)OCCO3)c2ccc(F)cc2)CC1
d: CCCN1C(=O)C(Cc2nc3ccccc3c(=O)n2-c2ccccc2)c2cc(C)ccc21
Answer: d. CCCN1C(=O)C(Cc2nc3ccccc3c(=O)n2-c2ccccc2)c2cc(C)ccc21
