A monomial is an expression that consists of a single term. It can be a number, a variable, or a product of numbers and variables raised to non-negative integer powers.
Among the options provided:
1. \( \frac{9}{x} \) - This has a variable in the denominator, so it is not a monomial.
2. \( 20x^{11} - 3x \) - This expression has two terms, so it is not a monomial.
3. \( 11x - 9 \) - This also has two terms, so it is not a monomial.
4. \( 20x^{11} \) - This is a single term and meets the criteria for a monomial.
Therefore, the monomial among the options is \( 20x^{11} \).
