Identify the true statement regarding Daniel cell:

In a Daniell cell, the copper half-cell is the cathode where Cu²⁺ ions are reduced to Cu, consuming positive charge. To maintain electrical neutrality, K⁺ cations from the salt bridge migrate into the copper half-cell, balancing the charge. Option A is false because zinc ions do not flow across the salt bridge; typically, K⁺ and Cl⁻ ions move. Option C is false because oxidation occurs at the zinc electrode, not copper. Option D is ambiguous: conventional current flows from copper to zinc externally, but the term 'current' may be interpreted as electron flow in some contexts. Thus, B is clearly correct.
