Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 7.213\% 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] CCC(C)NC(=O)CSc1ncnc2sccc12
[b] O=C(Nc1ccccc1)Oc1ccccc1N1CCOCC1
[c] CCCn1c(=O)c(C(=O)NCc2ccncc2)c(O)c2ccccc21
[d] O=C(Nc1cccc(NC(=O)c2cccs2)c1)c1ccc2c(c1)OCO2
Answer: b. O=C(Nc1ccccc1)Oc1ccccc1N1CCOCC1
