Answer 1

Hint: In the English language, there are eight pieces of speech: noun, pronoun, verb, adjective, adverb, preposition, conjunction, and interjection. The part of speech describes how a word works both grammatically and in terms of context within a sentence. When used in various ways, a single word may act as more than one part of speech.

Complete answer:
There are several moments when we need to explain a recent occurrence or action, and this often involves repeating what someone said. A social situation, as well as a work email or presentation, are examples of such times. There are two forms of speech used to explain what people said: direct speech and indirect speech (or reported speech).
Direct speech
One choice for expressing what someone said is to use direct expression. When we actually echo what someone says while placing the word between speech marks, we use direct speech:
“Can you solve this problem?” He asked me.
We may use indirect speech to report what someone said without using speech marks and without actually using the same phrases (also called reported speech).
When reporting a question, you must turn the interrogative form into an affirmative sentence by reversing the verb tense, as in normal recorded expression.
We may report two types of questions: yes/no questions and questions that begin with a question word like "what," "where," and so on. When reporting a yes/no question, we use the word ‘if.'

Hence, the correct answer is option ‘A’.

Note: If the knowledge in direct speech is still real, we don't always need to shift the tense to the past (but this is just for general truth, and even then we normally want to change the tense): "The sky is blue," says the speaker directly. She claimed (that) the sky is/was blue in her voice.
