Given below, is the result of a complementation test for seven independent mutants (A to G). '+' represents complementation; '_' represents non complementation. Based on the above, which one of the following conclusions is correct


a) The mutations can be ordered in a three cistron as A-G-B-C-D-E-F

b) All mutations belong to a single cistron, but their order cannot be determined.

c) There are three cistrons, mutations A and G represent one cistron, B, C and D represent the second cistron and E and F represents the third cistron.

d) There are three linkage groups, mutations A and G  represent linkage group-I, B, C and D represent linkage group-II, and E and F represents linkage group-III

Light reactions of photosynthesis are carried out by four major protein complexes: Photosystem I (PSI), photosystem II (PSII), the cytochrome b6f complex and ATP synthase. The following are certain statements on PSII:
a. Red light absorbed by photosystem II (PSII) produces a strong oxidant and a weak reductant.
b. Far-red light absorbed by photosystem II (PSI) produces a weak oxidant and a strong reductant.
c. The strong oxidant generated by PSII oxidizes water,
d. The strong reductant generated by PSII oxidizes water
