Problem statement: Answer the multiple-choice question.
Question: Which drug exhibits a 11.825\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
[a] CCCCC(=O)N/N=C(/C)C1=C(C)C(C)(C)OC1=O
[b] O=C(N/N=C/c1cccc(Cl)c1)C(c1ccncc1)N1CCOCC1
[c] Cc1ccc(N2CCN(C(=O)N3CCOCC3)CC2)c(C)c1
[d] S=c1[nH]cc(-c2ccccc2)n1-c1cccc(Cl)c1
Answer: a. CCCCC(=O)N/N=C(/C)C1=C(C)C(C)(C)OC1=O
