The answer is a Voltameter option D use in electrolysis as it contains the electrode, the elecrochemical cell and electrolytes.

I believe this is an error.
An ammeter is used to measure the electric current flowing during electrolysis.

While a voltmeter measures potential difference and a galvanometer detects small currents, an ammeter directly quantifies the current involved in the electrolytic process.
