Problem statement: Answer the multiple choice question.
Question: Which drug has a 4.795\% 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] Cc1ccc(C)c(N(CC(N)=O)S(C)(=O)=O)c1
[b] CCCc1ccc(-c2ccc(/C=C/C(=O)O)cc2)nc1
[c] COc1cccc(C(=O)Nc2nc3ccccc3s2)c1
[d] O=C(N/N=C/c1c[nH]c2ccc(Br)cc12)c1ccc2c(c1)OCO2
Answer: b. CCCc1ccc(-c2ccc(/C=C/C(=O)O)cc2)nc1
