Can someone help me evaluate this infinite square root expression? I can’t seem to find a way to simplify it.

I tried to separate the 5 into 1 + 4 and the 11 into 8 + 3 and so on for the next number. This isn’t like any other problems with nested radicals that i’ve solved. I hope i can learn something from this problem. Please help me! :) $$\sqrt{1+\sqrt{5+\sqrt{11+\sqrt{19+\sqrt{29+\sqrt{...}}}}}}$$

Side note: This is a multiple choice question with the choices are as follow: A. $\frac{1}{2}$ B. 1 C. 2 D. $\sqrt{3}$ E. $\sqrt{2} - 1$
