which one is correct and why

Suppose town A has a more inelastic demand for labour than town B, but the supply of labour is similar in both places . Both economies initially have some structural unemployment.An increase in the minimum wage will:

1. lead to a smaller reduction in employment in economy A than B, and lower unemployment
2. lead to a smaller reduction in employment in economy A than B, but higher unemployment.
3. lead to a larger reduction in employment in economy A than B, but lower unemployment
4. lead to a larger reduction in employment in economy A than B, but higher unemployment.
5. Nothing will happen to employment in either city as the minimum wage is lower than the equilibrium wage.
