• (1) Statement-I is false but Statement-II is true
• (2) Statement-I is true but Statement-II is false
• (3) Both statements are false
• (4) Both statements are true

Step-by-step solution

Why the other options are wrong

• (1) Statement-I is in fact true: a vernier division is made smaller than a main scale division so that a coincidence shifts along the scale.
• (3) Statement-I is true, so 'both false' cannot hold.
• (4) Statement-II is false: the vernier constant is one main scale division divided by the number of vernier divisions, not multiplied.
