Text Solution

Verified by Experts

The correct Answer is:
A
Paramagnetism depends upon number of unpaired electrons, more the number of unpaired electrons more the paramagnetic property. Mn has `d^(5)` configuration (five unpaired electrons) hence it is highly paramagnetic. Zn has `d^(10)` configuration (All electrons are paired)
Co has `d ^(7)` configuration (Three unpaired electrons)
