Jordan structure of an operator with a given annihilating polynomial

Let T:C7→C7T:\mathbb C^7\to\mathbb C^7 be a C\mathbb C-linear operator with eigenvalues 2,32,3 and 55. Consider the subspace

W:={v∈C7:(T−5I)kv=0 for some integer k>0}W:=\{v\in\mathbb C^7:(T-5I)^kv=0\text{ for some integer }k>0\}

of C7\mathbb C^7. Suppose that (T−2I)2(T−3I)2(T−5I)2=0(T-2I)^2(T-3I)^2(T-5I)^2=0. Which of the following statements are necessarily true?
