Detailed Solution

Concept- We will find no predecessor in the first natural number, where no predecessor means that the number is not a natural number. Predecessor of a number is 1 less than a number, while the successor is 1 more than the number.
Natural numbers are

1, 2, 3, 4, 5 . . . . . . . . . . . . . . . . . . n .

1 is the first natural number. Therefore, it will not have a predecessor because predecessor of any number

x = x - 1 .

And

1 - 1 = 0

Therefore, 1 will be a number that has no predecessor.
Hence, the correct answer is option 3.
