Answer:
Resistance of a wire is directly proportional to length and inversely proportional to cross sectional area . So whenever a wire is stretched its length increases and cross sectional area decrease . According to above proportionally the resistance of wire will increase .

This is the false statement.
Reason:
Resistence of wire is directly proportional to its lenghth.
When length of conductor increases resistance also increases.
