Thank you for the opportunity to help you with your question!

A regular nonagon has 9 sides of equal length

Formula for interior angle of a regular polygon  = 180*(n-2)/n degrees

n represents number of sides in regular polygon

here, n = 9

so, angle = 180*(9-2)/9 = 180*7/9  = 140 degrees

Answer is Option A. 140 degrees
