Central Board Of Secondary Education [CBSE] — questions in exam

With due veneration
I am a student of class 10th.
I want to complain about two questions of our class.
Code no.- 31/1/3
Set-3
First of all question no. 14 in which according to ncert the answer is (A) i. E. Both the statements are correct and r is the correct reason of assertion. This answer is right as solar cooker is made up of glass cooker to reduce the escape of heat but some of the solar cookers are also made up of concave mirror. There for option (A) and (C) both are correct according to google. And plane mirror are responsible for greenhouse effects everyone knows i have attached a screenshot of google regarding this topic. Therefore both the answers must be given number but the best answer is option no. (A).

Next question i want to complain about a question of all sets.
The question no. Of the question is q.29.
In that question in some of the papers the whole question was not printed properly because which students attempted it as they understood some who were not able to read that they have to give reason attempted without reasons because reason was written on one corner.
Please give extra marks for the questions to whom one had attempted the question without reason and unable to understand question. Around 10-15 students of my class had not written because of the reason. When other children asked them about the question they said that we had attempted without reason or written the name of element.

This question can result in the failure of the students in passing or scoring good marks.
Please see on this query accordingly.
