Answer: Publicity
Explanation:
From the question, we are told that a small agrichemical laboratory with a very small marketing budget develops a seed that produces grass, which grows two-inches high and no higher.
Since the laboratory has a small marketing budget, the promotional element it can use to let others know about its discovery will be publicity.
Through publicity, the company can give out vital information about its new discovery. By doing this, the public will be aware of the innovation. Publicity is a marketing and promotion component.
