The given five three-digit numbers are: 721, 145, 342, 372, 547.

First, let's arrange these numbers in descending order:

Original order: 721, 145, 342, 372, 547

Descending order: 721, 547, 372, 342, 145

Thus, only the number 721 remains in its original position.

Hence, the correct answer is "Option 2".
