Question: In SMS Data De-compression, when the bit 7 of a header octet in the input data buffer is set to 1, what action is taken based on the lower 7 bits of this header octet?
Option 1: The 'slice length' and 'slice offset index' are extracted for copying a data slice within the output buffer.
Option 2: The number of literal octets to follow is determined, which are then written to the output data buffer.
Option 3: The input data buffer reading position is incremented by the value represented by the lower 7 bits.
Option 4: The output data writing position is reset based on the binary value of the lower 7 bits.
Explanation: When bit 7 of a header octet is set to 1, it indicates literal octets follow. The lower 7 bits specify how many, which are then directly written to the output data buffer, incrementing both input and output position pointers by the block size (number of literal octets), efficiently decompressing SMS data.
