Correct option is C
Statement I is true because simple text editors typically have fewer editing features than word processors. For example, simple text editors may not have features such as spell checking, grammar checking, or the ability to format text with different fonts and styles.
Statement II is false because files created with simple text editors can be opened with word processors. Word processors are designed to be able to open and read a variety of file formats, including simple text formats like plain text (TXT) and Rich Text Format (RTF).
Therefore, the only correct answer is (c) Statement I is true but statement II is false.
