Find the options which is related to the third figure in the same manner as second figure is related with the first figure. (First figure is the leftmost figure.)

To find the correct option related to the third figure in the same way that the second figure is related to the first figure, let's analyze the patterns:
Let's examine the options to determine which one matches this transformation:
The option shown in the image above is the horizontally flipped version of the third figure, matching the transformation rule observed from the first two figures. Therefore, this option is correct.
Thus, the answer is: 
Which figure should replace the question mark (?) if the following figure series were to be continued?

Select the option in which the given figure X is embedded (i.e., contains figure X in the same form).

Select the option figure in which the given figure (X) is embedded as its part (rotation is NOT allowed).

Identify the figure in the options that when put in place of the question mark (?) will logically complete the series.

Select the figure from among the given options that can replace the question mark (?) in the following series.
