B. 1.25

Step-by-step solution

The given circuit consists of four parallel branches connected between the left and right common vertical wires. Let's find the equivalent electromotive force (EMF) and resistance for each branch: For the top three active branches, each contains three 5 V cells and three 3 resistors in series. Equivalent EMF of each active branch, E = 5 + 5 + 5 = 15 V . Equivalent resistance of each active branch, R = 3 + 3 + 3 = 9 . Since these three identical active branches are connected in parallel, we can replace them with a s
