Central Board Of Secondary Education [CBSE] — wrong question in class 10 science question paper

Respected sirs,
Today (16-march-2018) was are science test. My question paper set is 2 and code no. Is 31/2. There was a wrong question in section a. Question no. 10 the 'or' question in which we were asked to identify a salt added in pakoras to make it tasty and crispy. The answer to this should have been baking soda but further the question added that the ph of the salt is 14. Baking soda is a mild base with it's ph below 10. Thus it's not possible that the answer to the question is baking soda. Many students have written caustic soda as answer because its ph is 14. Further the question asked about the formation and applications of the salt, making it a 3 marker question. Sir i would like to request you to please take note of this and make sure that students should not be disadvantaged because of this error. I humbly request you to please take suitable action. Thank you
