Can you please verify if these 3 different orders are correct:

weakest electrolyte to strongest electrolyte:
================================
a)0.1M NaCl,0.1 M NaNO3,0.1M Ca(NO3)2,0.1M Al(NO3)2

b)
0.1 M NaNO3, 0.2 M NaCl, .1M Al(NO3)2, 0.2M Ca(NO3)2

c)
0.1M HF,0.1M HNO3, 0.2M CH3COOH, 0.2 M HCl

Question is not very clear .
0.1M NaCl,  0.1 M NaNO3,  0.1M Ca(NO3)2,  0.1M Al(NO3)3
First is correct and it is based on number of ions formed in the solution .
0.1M NaCl,0.1 M NaNO3,0.1M Ca(NO3)2,0.1M Al(NO3)3
This one is also correct because number of ions formed in the solution are increasing.
0.1M HF,0.1M HNO3, 0.2M CH3COOH, 0.2 M HCl
this one is wrong
CH3COOH is a weak acid with very low dissociation constant and even lesser than HF weak acid.
Order should be
CH₃COOH ,HF ,HNO₃ ,HCl
