In each of the box, the line inside the hexagonal is changed to it's point of connection.

In the first, second and third box, the line is connected to AC, AD and AE respectively.

In the same way, in fourth and fifth box, the line is connected to BD and BE respectively.

Similarly, in the sixth box, the line will be connected to BF.

As per the above given logic, the required figure is available in option (a).

Hence the figure given in option (a) will come in place of the question mark.
