List all the elements of the following sets:

F = {x : x is a consonant in the English alphabet which precedes k}.

The vowels are a, e, i, o,u


The letters before k are a, b, c, d, e, f, g, h, i, j, k


Thus the consonant before k are b, c, d, f, g, h, j


So, the elements of the sets are b, c, d, f, g, h, j


F={b, c, d, f, g, h, j}
