The correct answer is:
(b) False
EDTA (ethylenediaminetetraacetic acid) is a chelating agent commonly used in bioprocess engineering, particularly in animal cell cultures and other biochemical applications, to bind metal ions and regulate their concentration in the medium.
EDTA is generally considered to be non-carcinogenic based on available data. While EDTA itself is not considered a carcinogen, it is important to note that it is not metabolized by the body and can bind essential metals, potentially interfering with biological processes if used improperly. However, its use in typical concentrations for cell culture does not pose a carcinogenic risk.
Thus, False is the correct answer.
