Task: Answer the multiple choice question.
Question: Which drug exhibits a 2.572% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
[a] COc1cc(OC)cc(C(=O)N2CCN(c3ccccc3F)CC2)c1
[b] CCOC(=O)CC1C(=O)NCCN1Cc1cccc(C(F)(F)F)c1
[c] N=c1oc2cc(O)ccc2cc1C(=O)Nc1ccc(Cl)cc1
[d] O=C(c1ccc(COc2ccc(Br)cc2)o1)N1N=C(C(F)F)CC1(O)C(F)F
Answer: d. O=C(c1ccc(COc2ccc(Br)cc2)o1)N1N=C(C(F)F)CC1(O)C(F)F
