Final Answer:
12 units.Thus the option C is corect.
Step-by-step explanation:
The length of X is determined by the option with the correct measurement, and in this case, it is option (c) 12 units.
To explain further, the answer is obtained by evaluating the given options and selecting the one that represents the correct length of X. In this context, each option (a, b, c, and d) proposes a specific length for X, and after careful consideration, the correct answer is identified as 12 units. This determination is based on the information provided in the question.
Now, let's delve into the mathematical reasoning behind this selection. The given options are essentially choices for the length of X. By the process of elimination or direct evaluation, it can be established that the accurate length corresponds to option (c), which is 12 units. No additional calculations are needed, as the information in the question and the available choices are sufficient to make this determination.
In summary, the length of X is confirmed to be 12 units based on the provided options. This conclusion is reached through logical deduction and a careful consideration of the information presented in the question and the available answer choices.
