Let's analyze each of the given options to determine which one is a whole number.

1. [tex]\(\frac{2}{5}\)[/tex]:
- This is a fraction. When we convert it to decimal form, we get [tex]\(0.4\)[/tex]. Since [tex]\(0.4\)[/tex] is not a whole number, [tex]\(\frac{2}{5}\)[/tex] is not a whole number.

2. 98:
- This is a whole number because it is a positive integer without any fractional or decimal component.

3. 0.86:
- This is a decimal number. Since it has digits after the decimal point, it is not a whole number.

4. 35%:
- To convert a percentage to a decimal, we divide by 100. Thus, [tex]\(35\%\)[/tex] becomes [tex]\(\frac{35}{100}\)[/tex] or [tex]\(0.35\)[/tex]. Since [tex]\(0.35\)[/tex] is not a whole number, 35% is not a whole number.

After reviewing all the given options:
- [tex]\(\frac{2}{5}\)[/tex] is not a whole number.
- 98 is a whole number.
- 0.86 is not a whole number.
- 35% is not a whole number.

Thus, the correct option which is a whole number is 98.
Therefore, the valid choice is the second option in the list.
