In this note<strong>‎</strong>, <strong>‎</strong>we show that von Neumann regular McCoy rings are abelian<strong>‎</strong>. <strong>‎</strong>This gives a <strong>‎</strong>positive<strong> </strong>answer to the question rised in <strong>‎</strong> <strong>‎</strong>Comm<strong>‎</strong>. <strong>‎</strong>Algebra  42 (2014) 1565- 1570.” https://jsciences.ut.ac.ir/article_82140_00fdf1a1ff5378856adfa8d64d941eb6.pdf
