Bit error rate is the number of bits sent per data .

In 10 hrs , we sen 512 bit error 

so in 1 sec, we can send = 0.0142 bit error.

hence error rate is 0.0142/2.048 x 10^6

6.944 x 10^-9

Answer : A

Error rate  = Error bits/time  
Error rate = 512/36,000 Mbps
Bandwidth = 2.048 Mbps
Error rate = Error rate /Bandwidth 
Error rate = (512*/36,000)/2.048 *10^6
= 0.1422/2.048 = 6.9*10^(-9)
