$\huge\mathbb\fcolorbox{pink}{lavenderblush}{❀Answer❀}$

(a) It is because the filaments of anthers are united and clubbed together in 2 bundles. Nine out of ten stamens in a pea plant form a stamina tube. The tenth is free.

(b) It is because both the female and male reproductive structures are absent.

(c) Sepals of the Salvia are petaloid as 3 sepals are red in color and united as petals. Therefore, they are not differentiated from the petals.
