Final answer:
d) [NaN NaN NaN NaN NaN NaN] instructions for ~~x, it's impossible to compute the value of z from the given vectors x and y.
Step-by-step explanation:
The symbol ~~x in programming languages usually represents a bitwise NOT operation, but in this context, it seems like a typographical error or a placeholder. There isn't a clear definition or operation associated with ~~x. As a result, the value of z isn't defined based on the given vectors x and y. Therefore, the resulting value of z will be an array of NaN (Not a Number) of the same size as x or an undefined value. Hence, the answer is d) [NaN NaN NaN NaN NaN NaN].
It's important to note that without a defined operation or specific instructions for ~~x, it's impossible to compute the value of z from the given vectors x and y.
