Correct Option - 1
Detailed Solution:

The magnetic moment of an ion is determined by its number of unpaired electrons (n). For the given lanthanide ions:

o   Ce? has 0 unpaired electrons (4f? ).

o   Eu³? has 6 unpaired electrons (4f? ).

o   Gd³? has 7 unpaired electrons (4f? ).
Gd³? has the highest number of unpaired electrons and therefore
