First of all, Ha and An have the same letter A and the same graphic circle; AN and TN have the letter n that they think they can, and the same graphic pentagon.

So we can think that A stands for circle, N stands for pentagon, H stands for heart, and T stands for lightning.

It can be determined that NH stands for Pentagon and heart.

Look at the position of the graph. The figures in HA and AN are all round in front, that is, the figure represented by A is put in front. It can be concluded that the graphs arranged in alphabetical order and TN also conform to this law.

So in NH, the graphic center represented by H should be put in front, and the possible answer is C or D.

Continue to look at the graphics represented by HA ANd an. The positions of letters and figures are different. The figures are arranged in alphabetical order, while the position of A in the combination of two letters is different, while the figures are hollow and solid. When A is in the back row, the circle is solid, and when A is in the front row, the circle is hollow. Observing the figure of TN also conforms to this law.

So the figures represented by NH and N should be hollow, that is, hollow pentagons, and H should be solid hearts.

The final answer is D.
