1. Only statement 1 is sufficient but statement 2 is not sufficient. → False Statement 1: On the 7th day of a month. From statement 1, we cannot find when is Yuvi's wedding anniversary. 2. Both statement 1 and statement 2 are sufficient independently. → False As statement 1 is not sufficient independently. 3. ​Only statement 2 is sufficient but statement 1 is not sufficient. → False Statement 2: The month has 29 days only in a leap year. Only February has 29 days in a leap year. So, from this statement, it is clear that Yuvi's wedding anniversary is in the month of February, but the date of Yuvi's wedding anniversary cannot be stated from this statement. So, only statement 2 is not sufficient. 4. Both statement 1 and statement 2 are sufficient together. Statements: 1: On the 7th day of a month. 2. The month has 29 days only in a leap year. From 1 we know the date and from 2, we know the month. So, Yuvi's wedding anniversary is on the 7th of February. Hence, ‘Both statement 1 and statement 2 are sufficient together’ is the correct answer.
