Detailed Solution

The above statement is false.
For an object to have a lustrous property, it should be metallic and have light-reflecting properties. But here, rubber is not metallic. So, it has no lustre and cannot reflect light, so it can never be lustrous. Also, notebooks fall under the same category and are made of paper which again has no lustre and is opaque.
 The corrected statement would be, “Neither Rubber nor Notebook has lustre”.
