Task: Answer the multiple-choice question.
Query: Which drug exhibits a 2.332\% 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 other words.
Options:
a.) O=C(Nc1ccc(C(=O)N2CCOCC2)cc1)Nc1ccc(Cl)cc1Cl
b.) COC(=O)c1c(NC(=O)CN2C(=O)C(=O)N(C(C)C)C2=O)sc(C)c1C
c.) CN(Cc1nc2ccccc2c(=O)[nH]1)Cc1cc(=O)oc2ccc3ccccc3c12
d.) Cc1cc(C)nc(NC2=NCCN2C(=S)Nc2c(C)cccc2C)n1
Answer: a. O=C(Nc1ccc(C(=O)N2CCOCC2)cc1)Nc1ccc(Cl)cc1Cl
