we need to calculate effective annual rate and then we choose lendor whoose effective rate is lower
effective rate = (1+per period rate )^no of compounding periods

effective rate is (1+0.11345227/52)^52 - 1 = 12%
B) 10.934509% pa (semi annual compounding )
effective rate = (1+ 0.10934509/2)^2 -1 =11.23%
C)0.218177% weekly rate
effective annual rate = (1+0.00218177)^52 -1 = 11.99%
D)2.873734% quarterrly rate
effevtive annual rate = (1+0.02873734)^4 -1 = 11.99%

interest% = (2508.8 -2000)/2000 = 25.44%(for 2 years )
