Answer:
b. When an array is created, the number of elements must be placed in square brackets following the type of element being stored.
Explanation:
In Java an uninitialized array contains null values. Thus statement c is true as well.
Also generally for initializing and displaying array elements a for loop is used. Hence statement d is also correct.
In Java syntax for declaring an array is as follows:
Array declaration:
type [] array_name ;
Array instantiation(memory allocation):
type [] array_name = new array_name [size of array];
From the above it can be seen that the statement a is true and statement b is false as number of elements in array are not mentioned after the type.
Hence the correct answer is b.

Explanation:
cot x = cos x / sin x
tan x = sin x / cos x
(Find common denominators)
cosx/sinx * cosx/cosx = cos^2x/sinxcosx
sinx/cosx * sinx/sinx = sin^2x/sinxcosx
(Now we can combine them)
csc / (sin^2x+cos^2x / sinxcosx)
(Simplify)
csc*sinx*cosx / sin^2x+cos^2x
sin^2x + cos^2x = 1
csc*sinx*cosx / (1)
csc*sinx*cosx
csc = 1/sinx
1/sinx*sinx = 1
(1)*cosx = cosx
