Question

Which taxonomic category is less general in characters as compared to family

Answer 1

Try to remember this,
K P C F G S = Keep Pots Clean, Family Gets Sick

K = Kingdom

P = Phylum

C= Class

F = Family

G = Genus

S = Species

These seven obligate categories are arranged in descending order starting from Kingdom to Species.
The number of similar character specificity (decreases) as we go from lowest rank (species) to highest rank (kingdom) .

So,all the categories above family have less general in characters as compared to family .These include Kingdom,Phylum,Class.
As an answer specific to the question,we can take the "Class" which is closer to family.
