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

People who suffer from thyroid adenomas have constitutively activated G proteins in some cells of the thyroid gland. Tumor cells not only secrete copious quantities of thyroid hormones but also divide and grow excessively. Based on these observations, in what kind(s) of signal transduction pathways do the mutant G proteins participate?
