Donor strain of bacteria with His+ Ara+ Met+ Leu+ Cys+ Lys+ is infected with phages to map the donor chromosome with generalized transduction .The Phage lysate from bacterial cell is collected and use to infect second strain of bacteria that are His- Ara- Met- Leu- Cys- Lys- . Different transducing phages are selected on using different minimal media and their presence of growth (+) and absence of growth (-) given in table

Which of the following is an incorrect statement about the regulation of populations?
A) The logistic equation reflects the effect of density independent factors, which can ultimately stabilize populations around the carrying capacity.
B) Density-independent factors have an increasingly greater effect as a population’s density increases.
C) High densities in a population may cause physiological changes that inhibit reproduction.
D) Because of the overlapping nature of population-regulating factors, it is often difficult to precisely determine their cause-and-effect relationships.
