Explanation:
To answer this question, we need to understand the given information and evaluate each option based on it.

The question provides a series of blank spaces, labeled as a), b), c), and d), and asks for the correct option. It also provides a set of instructions on how to answer the question.

Let's evaluate each option based on the given information and the provided rules:

a) This option is identified as the correct answer. However, the reason for selecting this option is not provided. Therefore, we need to further analyze the remaining options.

b) No information or explanation is given for this option. Without any supporting details, we cannot determine if this option is correct or not. Therefore, we can eliminate this option.

c) Similar to option b), there is no information or explanation provided for this option. We cannot determine its correctness without any supporting details. Hence, we can eliminate this option as well.

d) Again, there is no information or explanation given for this option. Without any supporting details, we cannot ascertain its correctness. Therefore, we can eliminate this option.

Based on the above analysis, option 'A' is the only one that is identified as the correct answer. However, it is important to note that the given instructions do not provide any specific criteria for evaluating the options. Therefore, it is essential to consider the context and provided information while answering the question.

In conclusion, option 'A' is the correct answer, but the lack of supporting details and explanation for the other options makes it difficult to fully justify the choice. It is always important to carefully analyze the given information and instructions to arrive at the correct answer in any examination.
