To determine the left child of the node V, we need to look at the row immediately below it in the binary tree. From the given portion of the memory, we can see that the row below V is:
0010 1110 1010 0011
This can be split into two segments, each of 16 bits:
0010111010100011
We know that the left child of V will be the 16 bits immediately following the 16 bits representing V in memory. Therefore, the left child of V is represented by:
10100011 10001101
This corresponds to the node Y in the binary tree, which is represented by the memory address:
11ea32c0_19c8_2ca3_96e7_3fc43a23e80b_TB1806_09
Therefore, the correct answer is option C, Y.
