there is no widely recognized term or acronym "GCTM" associated with any specific institution, organization, or concept in India. However, the information available to me might be outdated.If "GCTM" refers to something specific that has emerged or gained prominence after my last update, I recommend checking the latest sources, such as news articles, official websites, or government publications, for the most current information.If "GCTM" stands for something else or if you have additional context, please provide more details so that I can better assist you.
