Horizontal micro programming:

 1)  Each control signal itself  present in control word So no need of signal decoders, To represent one control  signal we need 1-bit  so A, C is true

 2)  In Vertical micro programming control word  contain log(no of control signals) bits to represent control signals.  

 Ex: suppose 16 control signals are there, In HmP  16 bits, in VmP  log16 = 4 bits are required

 so B is true   

 Finally Option D is Answer
