Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. Since.
The corrected sentence would be: "We have to link our soul with God and body with the physical world for substance. Since the formless God is invisible to the naked eye, our mind often wanders wherever it goes."
In this context, "since" indicates a reason or cause, connecting the idea of linking the soul with God and the body with the physical world to the fact that the formless God is invisible.
