Regular Expression (Doubt)

Question

Here I thought the answer should be A and D but in the test series answer it is written as only D is the answer.
My doubt is : A should not be generating 100 as a substring if it is generating 100 as a substring can you please explain?

Comments

Option A. 100 can be generated like

0*(1*0)(1*0)(1*0)* = $\epsilon$.10.0.$\epsilon$ = 100

---

If you look carefully, you will see that A generates all possible strings, i.e. Σ*
