The term `greenwashing` refers to the act of misleading consumers by giving a false impression that a company`s products are eco-friendly or environmentally sound, hence, the correct answer is Option 1. Now, let`s dissect the other options.

Option 3 refers to ignoring the ecological consequences during infrastructure development, which can be considered irresponsible, but it doesn`t directly relate to the concept of greenwashing. Option 4 describes making provisions for environmental costs in a government project or programme. This is a responsible practice and also not related to the concept of greenwashing. Therefore, Option 1 is the best answer that describes `greenwashing`.
