Helllo ! This is from TSA 2021 set. The answer is D but I couldn’t figure out it. Please help me solve this question. Thank you in advance.
A signal transmitter transmits a message in binary form. (In other words, the message is coded in ‘bits’. Each bit is represented either by the digit ‘1’ or by the digit ‘0’.)
To add an element of security, the signal is embedded within other random bits (so that there are other 1s and 0s before and after the message), creating a 26-bit transmission.
A particular 12-bit message is transmitted as follows:
01100010111001010011000100
The same message is transmitted again, as follows:
10101001111011100101000101
What is the 12-bit message contained within these two transmissions?
A 001010011000
B 001111011100
C 010011000100
D 101110010100
E 111101110010
