Let us begin by defining the different types of numbers:
A prime number that is divisible only by itself and 1
A composite number is a positive integer that can be formed by multiplying two smaller positive integers.
Natural numbers are a part of the number system which includes all the positive integers from 1 till infinity
(a)
[tex]primes\text{ n composite = \textbraceleft1\textbraceright}[/tex]
This is false because 1 is not a composite number and it is not a prime number
(b)
[tex]primes\text{ u composite = \lparen Natural numbers\rparen}[/tex]
This is false because 1 is a natural number but it is neither prime nor composite
(c) 1 is a member of primes
1 is a not a prime number so it is not a member of primes
(d) (Primes) is a member of (Natural Numbers)
This is a true because a prime number is a natural number that is greater than 1 that is not a product of two smaller natural numbers
Hence, the correct option is Option D
