Taxation Law mein Ek Tricky Sawal: Deductions under Section 80C

Question: Mr. Sharma, ek company employee hai, jisne 5 lahakar (Rs 1 lakh) tak ka fixed deposit (FD) kharidkar investment kiya hai. Uski income 5 lakh rupee hai. Unka tax liability kya hai? Unka claim ho sakta hai kya FD ka deduction? Kya difference hai agar unhone 5 lakh rupee FD mein invest kiya hota (aam taur par aur majboot FD hai), lekin 2-3 mahine ki kam duration tak hai?

Tax ka concept simple hai, but problem ka solve karne ka tareeka naya. Apne mind mein kya soch rahe hain?
