Genetic pedigree

Can someone explain this? Idk why E its the correct answer.

Hi! here’s how i answered this question:

5 is X-linked recessive so not autosomal
4 could be Y-linked so not autosomal
3 could be explained by autosomal recessive

Choosing between 1) and 2) was more difficult:

1 as autosomal dominant works, offspring Pp have the trait
1 as autosomal recessive also works, offspring PP have the trait

2 as autosomal dominant works
2 can’t work as autosomal recessive as we have will not be able to produce the first offspring: pp x PP would give healthy Pp carriers

Let me know if i’m wrong or if you need me to upload the fully drawn out pedrigrees , hope this helps!
