खालीलपैकी कोणते/ती विधान/ने चूक आहे/त ?
a. 1968 मध्ये प्रथम भेट कर लागू करण्यात आला.
b. 1 एप्रिल, 1991 रोजी किंवा त्यानंतरच्या भेटवस्तूंवर भेट कर रद्द करण्यात आला.

The correct answer is Option C (Both a and b are incorrect).

Key Points:
• Introduction of Gift Tax: The Gift Tax was introduced in India by the Gift Tax Act, 1958 (not 1968). It was introduced based on the recommendations of the famous British economist Nicholas Kaldor to prevent tax evasion through the transfer of wealth as gifts to relatives and friends. Thus, statement 'a' is incorrect.
• Abolition of Gift Tax: The original Gift Tax Act of 1958 remained in force for forty years. It was finally abolished by the then Finance Minister Yashwant Sinha, effective from October 1, 1998 (not April 1, 1991). Therefore, statement 'b' is also factually incorrect.
• Re-introduction: It's important to note for exam perspective that the taxation on gifts was reintroduced in a different format under the Income Tax Act, 1961 via the Finance Act of 2004 (effective from September 2004), where gifts exceeding ₹50,000 received from non-relatives became taxable in the hands of the recipient under the head "Income from Other Sources".
• Conclusion: Since the introduction year (1958) and the abolition year (1998) in the given options are both wrong, both statements 'a' and 'b' are incorrect.
• Key Takeaway: Gift Tax was introduced in 1958 (Nicholas Kaldor's recommendation) and abolished in 1998. Both dates in the prompt are incorrect.
