The image presents a multiple-choice question regarding MATLAB code snippets. The question asks which of the given selection statements is logically equivalent to the provided code snippet: ### Original Code Snippet: ```matlab if y > 55 x = 55; if y > 44 x = 44; if y > 33 x = 33; end ``` ### Answer Choices: - **a.** ```matlab if y > 55 x = 55; else if y > 44 x = 44; else if y > 33 x = 33; else x = 33; end end end ``` - **b.** None of the choices is correct. - **c.** ```matlab if y > 55 x = 55; else if y > 44 x = 44; else if y > 33 x = 33; end end ``` - **d.** ```matlab if y > 55 x = 55; else if y > 44 x = 44; else if y > 33 x = 33; end end end ``` This question challenges the reader to understand nested conditional statements and how they affect the logical flow of a program. The structure of branching in code snippets is critical for determining the output based on different values of `y`.

**Equivalent MATLAB Switch Statement Question** Which of the following MATLAB `switch` statements is logically equivalent to the following code snippet? ```matlab if y == 33 x = 33; elseif y == 44 x = 44; elseif y == 55 x = 55; else x = 0; end ``` **Options:** (a) ```matlab switch y case 33 x = 33; case 44 x = 44; case 55 x = 55; end ``` (b) ```matlab switch y case 33 x = 33; case 44 x = 44; case 55 x = 55; otherwise x = 0; end ``` (c) ```matlab switch y case 33 x = 33; case 44 x = 44; ``` **Explanation:** The `switch` statement in MATLAB allows you to execute different code blocks based on the value of a variable, similar to an `if-elseif-else` structure. The equivalent switch statement to the given code snippet will need to include an `otherwise` clause to handle the case where `y` is not 33, 44, or 55. Thus, the correct option is (b).
