Task: Answer the multiple choice question.
Query: Which drug exhibits a 3.833\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a CS(=O)(=O)N(CC(=O)NCCc1ccccc1)c1cccc([N+](=O)[O-])c1
b Cc1ccc(-c2cc(C(=O)N/N=C/C=C/c3ccccc3)n[nH]2)o1
c CCN(CC)S(=O)(=O)c1cccc(C(=O)Oc2cccnc2)c1
d O=C(NCc1ccccc1Cl)c1ccc(S(=O)(=O)N2CCCC2)cc1
e CCOc1cc(C(N)=O)cc(Cl)c1OCC
Answer: a. CS(=O)(=O)N(CC(=O)NCCc1ccccc1)c1cccc([N+](=O)[O-])c1
