I would say A. If correct would atleast consider brianlist ehhe:)

Explanation: What is the job of researchers in the Astronaut Microbiome Project?
The true statements after evaluating the expression based on principle of commutativity and associativity are :
A: x + y = y + x
B; (x × y) × z = x × (y × z)
D: (x + y) + z = x + (y + z)
We are given;
x = a + bi
y = c + di
z = f + gi
Now according to properties of algebra, we know that;
- Commutative property states that with addition and multiplication of numbers, you can change the order of the numbers in the problem and it will not affect the answer. For example; a + b = b + a
- The Associative property states that; a × ( b × c) = b × (a × c) = c × (b × a)
Looking at the options :
A) x + y = y + x ; This is true as it follows Commutative property of addition
B) (x × y) × z = x × (y × z) ; This is true as it follows the Associative property.
C) x - y = y - x ; this is false as it does not follow both properties.
D) (x + y) + z = x + (y + z) ; This is true as it follows the Commutative property.
E) (x – y) – z = x – (y – z) ; This is False as it does not follow any of the 2 properties.
