A tension member with Pu3225 k is to consist of a pair of angles with a 3/8-in gusset plate between the angles at each joint. Use A36 steel and assume two lines of three 3/4-in o bolts in each vertical angle leg, 4 in on center. Consider only the angles shown in the double-angle tables of the AISC Manual. The member is assumed to be 12 ft long. Do not consider block shear. The lightest section for this member is:

Give me right solution according to the question. Urgent please

A tension member with Pu=225 k is to consist of a pair of angles with a 3/8-in gusset plate between the angles at each joint.
Use A36 steel and assume two lines of three 3/4-in bolts in each vertical angle leg, 4 in on center. Consider only the angles
shown in the double-angle tables of the AISC Manual. The member is assumed to be 12 ft long. Do not consider block shear.
The lightest section for this member is:
O a. 2L6 x 4x 1/2
O b. 2L7X 4 x 3/8
O c. 2L5 x 3 x 1/4
O d. 2L8 x 6 x 9/16
