Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 1.625\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a. CCN(CC)S(=O)(=O)c1cc(C(=O)Nc2ccccn2)ccc1C
b. CNS(=O)(=O)c1cccc(C(=O)OCC(=O)Nc2ccc(OC)cc2[N+](=O)[O-])c1
c. CCCSc1nnc(NC(=O)Nc2ccccc2OC)s1
d. CC1=C(C(N)=O)C(c2cccs2)n2nc(-c3cccc(Cl)c3)nc2N1
e. CCN(CCNC(=O)c1ccc2nc(-c3ccccc3NC(C)=O)c(=O)[nH]c2c1)c1ccccc1
Answer: a. CCN(CC)S(=O)(=O)c1cc(C(=O)Nc2ccccn2)ccc1C
