Best answer
Right answer is (a) True

The best I can explain: The given statement is true. Intelligent packing can serve as freshness indicator. It can be divided into external and internal indicator on basis of their use. External indicators are those which are attached outside the package. E.g. Time-Temperature & Microbial growth Indicator. Internal indicators are those which are placed inside the package, either to the head space of the package or attached into the lid. Eg. Oxygen Indicators, Carbon dioxide Indicators, Microbial Growth Indicators, Pathogen Indicators.
