$\emptyset \subset \{101, 102, 103,... , 200\}$
Work Step by Step
$\emptyset$____$\{101, 102, 103,... , 200\}$
By definition, an empty set is a subset of every set, and is a proper subset of every set except another empty subset, therefore:
$\emptyset \subseteq \{101, 102, 103,... , 200\}$
$\emptyset \subset \{101, 102, 103,... , 200\}$
