The position of floral organs in relation to the ovary can be categorized as follows:
Step 1: In Figure (a), the floral organs are attached at the same level as the ovary, so it is Perigynous.
Step 2: In Figure (b), the floral organs are also attached at the same level as the ovary, so it is Perigynous.
Thus, the correct answer is (4) (a) Perigynous; (b) Perigynous.

Three identical heat conducting rods are connected in series as shown in the figure. The rods on the sides have thermal conductivity 2K while that in the middle has thermal conductivity K. The left end of the combination is maintained at temperature 3T and the right end at T. The rods are thermally insulated from outside. In steady state, temperature at the left junction is \(T_1\) and that at the right junction is \(T_2\). The ratio \(T_1 / T_2\) is
