Low right arrows can be caused by which of the following?

When arrows hit low and to the right, one common cause is the string hitting the chest. This phenomenon typically occurs when the archer's form is not adequately in check, causing either the bow arm or the body to interfere with the path of the string during the release.

If the string makes contact with the archer’s clothing or chest, it can alter the flight of the arrow, pushing it downward and potentially to the right, depending on the specifics of the archer's position and alignment. This is particularly pertinent in archery, where precision in form and execution is crucial for consistent arrow flight.

The other options do relate to shooting errors but do not directly connect to causing an arrow to consistently fly low and right in the same way. For example, a weak bow arm may not necessarily result in a rightward deflection but might create instability in the shot overall. Similarly, canting the bow to the left can influence arrow direction, but more towards left deviation rather than low and right. Collapsing the bow arm typically affects the arrow's flight, but the specifics of downward trajectory due to string interference are more directly correlated with hitting the chest. Hence, string contact is a key factor for low right arrows.
