Final answer:
Among the expressions given, the only true statement is 69 < 70, which means 69 is less than 70.
Step-by-step explanation:
The question asks which expression is true:
- 3641 > 3840 is false because 3641 is less than 3840.
- 69 < 70 is true because 69 is less than 70.
- O160 < 150 is false because it's not clear what O160 stands for, but if it's assumed to be 160, then 160 is greater than 150.
- 8 > 104 is false because 8 is less than 104.
Therefore, the expression 69 < 70 is the only true statement among the choices provided.
