Consider the Space Time Diagram Below $O$ And $A$ Be $\Delta s_{O A}$

Multiple Choice

Consider the space time diagram below. Let the space time interval between events $O$ and $A$ be $\Delta s_{O A}$ , and let the space time interval between events $O$ and $B$ be $\Delta s_{O B}$ Which of these two space time intervals is larger? (Assume that the $y$ and $z$ coordinates of all these events are zero.)

A) $\Delta s_{O A}>\Delta s_{O B}$
B) $\Delta s_{O A}<\Delta s_{O B}$
C) $\Delta s_{O A}=\Delta s_{O B}$
D) There is no way to tell from this diagram.
