Both 1 and 3 will do. 1 would mean that you've found out that it's raining just now and made the decision. 3 would mean that it's been raining for a while today and you had time to make a plan.

Ignore Bilal. There is no such rule. He may have had a teacher who gave some test-taking advice along the lines "If you don't know the answer, choose an answer in the same tense as the question." Elena has a good explanation of the most likely expected answers. However, all four answers are possible under certain circumstances. 1 - It's raining today. (= It has been raining.) The decision to not play outside has already been made. So answer 3 ("we are not going to play..." fits the scenario. (I agree with Elena.) 2 - It's raining today. (= It has just started raining.) The decision to not play outside is being made now. So answer 1 ("we won't play..." fits the scenario. (I agree with Elena.) 3 - It's raining today. (= It will rain later in the day. This is a normal use of a present tense for a future situation that is regarded as certain.) Answer 2 ("we are not playing..." can be used to express a future event that is regarded as certain, particularly in spoken English. For "school" English, this structure is used mostly for personal activities. Answer 4 ("we don't play...") can be used to express a future event that is regarded as certain, particularly in spoken English. For "school" English, this structure is used mostly for transportation. For more information, consult English Grammar in Use 4th edition by Murphy. A paper copy is reasonably priced and there is a PDF available on the net. See unit 19 - Present tenses for the future See unit 20 - going to See unit 21 - will See Unit 23 - will and going to (will do - for a decision) (going to do - for an existing plan) However, in casual spoken English, answers 1 (units 21 and 23), 2 (unit 19), and 3 (unit 20) are common and answer 4 (unit 19) is possible.

Correct answer is number (3) as it is in accordance with the tense . See its " present continuous " . So the answer needs to be in the same tense too .

Thank you for all 😍😍😍

All three sentences work. Sentences three is more natural and it is using we + are. We= plural and "are" goes with plural it is the instinctive way a native would phrase it. I think this is what Bilal was trying to explain. But he gave the impression that present must bring about another present tense. It does not. Sentence 4 is incorrect.
