Explanation:
The thermite reaction is a redox reaction that is very important in metallurgy. The reaction is as follows;
2 Al(s) + Fe2O3(s) --> 2Fe (s) + Al2O3 (s).
In this reaction, aluminium is oxidized from 0 to +3 oxidation state while iron is reduced from +3 to zero oxidation state from left to right respectively as shown in the reaction equation above.
This reaction occurs at high temperature and as a result of this, it can be used to join metals at such high temperature. This is why the reaction can be used to join rail tracks.
Under Freytag's pyramid, the plot of a story consists of five parts: exposition (originally called introduction), rising action (rise), climax, falling action (return or fall), and dénouement/resolution/revelation/catastrophe. So our best bet would be A , because it shows more than the plot and it does not show how to analyze.
