Which of the following defines the set M={5,10,15,20}M = \{5, 10, 15, 20\}M={5,10,15,20} using set-builder notation?
{x∈Z:x is a multiple of 5 and 5≤x≤20}\{x \in \mathbb{Z} : x \text{ is a multiple of 5 and } 5 \le x \le 20\}{x∈Z:x is a multiple of 5 and 5≤x≤20}
{x∈Z:x is a multiple of 5 and x<20}\{x \in \mathbb{Z} : x \text{ is a multiple of 5 and } x < 20\}{x∈Z:x is a multiple of 5 and x<20}
{x∈Z:x is a factor of 20}\{x \in \mathbb{Z} : x \text{ is a factor of 20}\}{x∈Z:x is a factor of 20}
{x∈Z:x2=25}\{x \in \mathbb{Z} : x^2 = 25\}{x∈Z:x2=25}
