Remark
If there are 5 distinct zeros that means either that the x axis is crossed the x axis 5 different places or touched the x axis in 1 place out the 5. Touching in one place means that an even number of roots are the same.
So let's go through all of them to get an answer of 5.
A has 4 x intercepts. It is not the right answer. We need 5.
B has 4 x intercepts. It is not the right answer. We need 5.
C has 6 x intercepts. Not the one we want.
D has 5 x distinct zeros. The wording is a bit tricky. It does not matter than one of them just touches the x axis. There could be an even number of distinct zeros there, but it only counts as one root.
An example of such a graph is f(x)=

Multiples of 2: 2,4,6,8
Multiples of 6:6,12,18,24
Multiples of 12:12,24,36,48
Multiples of 25:25,50,75,100
Further explanation:
A multiple is a number that is obtained by multiplying an integer with that number.
We have to find multiples of given numbers:
So,
<u>1. Multiples of 2</u>
<u>2. Multiples of 6</u>
<u>3. Multiples of 12</u>
<u>4. Multiples of 25</u>
