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

In a single stage continuous extraction system. solvent is added to cell-free culture filtrate containing the product. If the partition coefficient of the product is 5. then to extract 90% of the product, assuming ideal single stage, the flow rate of solvent should be times the flow rate of the culture filtrate.
