Task: Answer the multiple choice question.
Question: Which drug exhibits a 21.449\% 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] O=C(Nc1ccc(C(=O)O)cc1)/C(=C/c1cccc(Br)c1)NC(=O)c1ccco1
[b] COc1ccc(N2CCN(Cc3nc4ccsc4c(=O)[nH]3)CC2)cc1
[c] Cc1onc(-c2ccccc2Cl)c1C(=O)NC(C)c1ccccc1
[d] O=C(CCCc1c[nH]c2ccccc12)NCc1cccs1
Answer: d. O=C(CCCc1c[nH]c2ccccc12)NCc1cccs1
