Task: Answer the multiple choice question.
Question: Which drug exhibits a 10.147\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
[a] Cn1c(C(=O)Nc2ccc(Cl)cc2)cc2cc(Cl)ccc21
[b] O=C(Cc1ccccc1)N1CCN(Cc2ccccn2)CC1
[c] CCOc1ccc(C2C3=C(CCCC3=O)Nc3nc(C(F)(F)F)nn32)cc1OC
[d] C=CCn1c(SC(C)CC)nc(O)cc1=O
Answer: a. Cn1c(C(=O)Nc2ccc(Cl)cc2)cc2cc(Cl)ccc21
