Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 13.138\% 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 additional words.
Options:
a: O=C(Nc1nnc(Cc2ccccc2)s1)c1ccccc1
b: COc1ccc(CCNC(=O)C2CCCN2C(=O)Nc2cccc(C(C)=O)c2)cc1OC
c: Cc1ccccc1NC(=O)c1ccccc1NS(=O)(=O)c1cccc2cccnc12
d: COc1ccc(N2CCN(C(=O)c3cc4cc(Cl)ccc4[nH]3)CC2)cc1
e: Cc1ccc(NC(=O)CC2OC(=O)c3ccccc32)cc1S(=O)(=O)N1CCCCCC1
Answer: d. COc1ccc(N2CCN(C(=O)c3cc4cc(Cl)ccc4[nH]3)CC2)cc1
