To determine a similarity in the way each text develops its argument, you'd need to specifically analyze the content and strategy used in both passages. However, based on your options, the most common strategies in persuasive writing would be referring to experts, using emotional language, or applying logic and reasoning.
If both passages indeed include emotional language or expert references, you could select that as the answer. If you are looking for a more logical approach that typically underpins many argumentative texts, "use logic and reasoning to develop their argument" could also be apt.
Without specific content from the passages, I can't definitively say which option to choose, but you can look for patterns in how each argument is built based on the strategies mentioned. Choose the one that both passages share prominently in their argumentation style.
