Step-by-Step Analysis
The question concerns languages over the alphabet T = {a, b} and their complements.
Option a: 'For every language L over T, the positive closure L* is infinite.' This is false because L* can be finite: for example, if L = ∅, then L* = {ε}, which is finite (indeed of......Login to view full explanationLog in for full answers
