Glyphosate resistance in plants can be generated by expressing in them transgenes that serve one of the following three purposes: 

(1) Overproduction of EPSPS enzyme 

(2) Encode an EPSPS enzyme that is tolerant to glyphosate

(3) Produce an enzyme that inactivates glyphosate

(4) Use a combination of the strategies (2) and (3)

Which of the above strategies can be used to make plants glyphosate resistant?

Following are certain statements are related to the effect of red and far-red light;

a) under a dense canopy much of the red light is absorbed by plant pigments, resulting in transmittance of mostly far-red light

b) Pr (red) has highest photon flux at 680 nm while Pfr (far-red) has highest photon flux at 730nm

c) Pfr far-red light–absorbing form, which is considered to be the physiologically active form of phytochrome

d) R:FR ratio is strongly affected by the presence of a canopy because chlorophyll absorbs far-red but not red light

Which one of the combinations of above statements is incorrect?
