Passing by reference is used if a parameter's data flow is two-way, into and out of the function.
C. two-way, into and out of the function.
<u>Explanation:</u>
If a function in programming language passing the parameter by reference means it only sending the address of parameter to a function. If any value is changed on reference parameter it will changed original value.
If parameter passed by value means it is one way, where value been send to the function.
Whereas by reference means it two-way, in and out of the function. Mostly it called as pointer.
It is available in c , c++, where declare of variable “*” or “&” address off.
3 radio buttons from the following code can be selected at any given time.
<u>Explanation:</u>
In any programming language end user prompts either checkbox or radio buttons.
Normally checkbox are used for end user to select true or false methods where return value will true if checkbox click or false, one or zero. It all depends how end user uses the checkbox in his or her programming languages.
Radio buttons are used to end user in the programming languages where to select one radio buttons out of given radio buttons.
Where each radio buttons are marked with own assigned values. Based upon user selecting the radio buttons return will be assigned value of selected radio button.
If select option is multiple, each category of radio button is placed in grouping.

Answer:
Answer explained below
Explanation:
The corners of the triangle are the primary colours; points along the triangle edges represent colours achieved by mixing 2 primary colours.
Points within the triangle represent quantitatively the colours obtained by mixing the 3 primaries in varying proportions.
The match can be written C ≡ aR + bG + cB, where C is the colour to be matched, R, G, B are the chosen primaries and a, b, c, record the amount of each primary. a, b, c, are the measure of the colour C.
Multiplying a, b, c by a constant factor just changes the brightness of the colour so usually a + b + c = 1 is chosen in suitable units.
In this way we can say that the relation between the Maxwell triangle and colour cube
