Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 16.532\% 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] Cc1ccc(NC(=O)C2CCN(S(=O)(=O)c3c(C)nn(C)c3C)CC2)c(Cl)c1
[b] Cc1c(C(=O)N2CCN(c3ccccc3)CC2)oc2c(Cl)cccc12
[c] COC(=O)C1C(c2ccccc2)C=CC(c2ccccc2)C1C(=O)O
[d] O=C(O)C(Br)CBr
[e] O=C(NCc1cccs1)C1CCC(=O)N(Cc2cccc(C(F)(F)F)c2)C1
Answer: d. O=C(O)C(Br)CBr
