Indicate the correct designation of the paired sex chromosomes.

The chromosomes, which predict the sex of individual organisms are known as sex chromosomes. For example, in humans, there are twenty-three pairs of chromosomes, and one of these pairs is considered as the sex chromosomes.  

An egg always constitutes a single X, while sperms carry either X or a Y. Thus, a female possesses two X chromosomes, while a male has one X and one Y. This is the process of predicting sex in humans. Hence, the correct designation of the paired sex chromosomes is XX in females and XY in males.

you didn't give any options but heres what i can tell you: an inference is likely to change based on additional observations. the latter is something that you have seen or sensed using your sensory organs while the former is like a conclusion out from what you have observed.
