Three identical wires with a linear mass density of 25 g/m are assembled to form an isosceles triangle with a base angle of 45 degrees.  The currents are equal, and the directions are as shown. The two base wires have a separation of 1.5 cm and are fixed to a bench. Calculate the value of the current that causes the top wire to get suspended, forming a base angle of 45 degrees.

• A. 110 A
• B. 140 A
• C. 96 A
• D. 160 A
