Task: Answer the multiple choice question.
Query: Which drug exhibits a 2.054\% 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 COc1ccc(/C=N/NC(=O)CNC(=O)c2ccc(S(=O)(=O)N3CCOCC3)cc2)cc1OC
b CC(=O)N1C(=O)N(C(C)=O)C2C1N(C(C)=O)C(=O)N2C(C)=O
c NC(=O)Cn1c(=O)n(CC(=O)N2CCCCC2)c(=O)c2sccc21
d Clc1cccc(Oc2ncc(CN3CCOCC3)s2)c1
Answer: d. Clc1cccc(Oc2ncc(CN3CCOCC3)s2)c1
