Fountains Abbey Obelisk Illusion

This is the third item that Dave Barlow sent me. He took this photo while on holiday at Fountains Abbey, UK, last year. When he got home he realized there was an illusion that the obelisk seemed as tall or taller than the church.

My question is, how tall is the obelisk seen here?

Taller than the church?
As tall as the church?
3/4 as tall as the church?
1/2 as tall as the church?
1/4 as tall as the church?
