To find three collinear points on plane $Y$, let's break down the information:

You are given multiple options for collinear points, and the question involves identifying three points that lie on the same straight line in plane $Y$.

The question content on the right seems to list points $Y, L, H, A,$ and $X$.

The correct approach is to visually or logically analyze which three points align on the same line within plane $Y$.

From the provided options:

• $X, H, L$
• $A, L, X$
• $A, X, n$
• $Y, A, L$
• $H, A, L$
• $H, A, X$

Let's analyze based on typical conventions:

1. Points $X, H, L$ often refer to collinear points, as they could lie on a line based on positioning.
2. Other options involve points like $n$, which might be out of scope, or combinations that don't appear on the same line.

Therefore, the most likely correct answer would be $X, H, L$.
