The correct answer is 7 , but why is this the answer ? since you asked :) just read below :

_____________________________________________________

An out-liar is a number that doesn't quite fit in, it should stand out from everything else.
No matter what type of number big or small, in this case the answer is 7.

Now that we know what the meaning of Out-liar is , you should obviously understand that the number 7 is the only number far away in distance from the rest.

This was my reason being for my answer , I really hope that you find my answer helpful.

The outlier number in the given data is:

A) 7

Outliers in data collection.

When data is collected for statistical analysis, one or more outliers are regularly obtained, that is, data that largely deviates from the regular behavior of the variable studied and that, if used within the study, could generate large variations in results.

As can be seen in the exercise, the data starts with a value of 23, then 34 and then 27, these first three data are characterized by being above 20, when we review the fourth data, with a value of 7, its variation with respect to the previous data is 20 units and 23 units with the following data (the fifth data is 30), in addition, such a high difference between one data and another in the sequence does not appear again, since the other difference of data is 11 units between data 1 and data 2, almost half.

For this reason, when a difference is so high that it is not repeated within the data cycle, option A is identified as the correct one.

As an attached image you will find a graphic example of an outlier data, which can be better visualized there.
