Here is the trick;
a(lsb) b c(msb)
a and b set to clear
So 110==4+2+0=mod-6.
a(lsb) b c(msb)
a and b set to clear
So 110==4+2+0=mod-6.

We get a high o/p at MSB ff is high. To get this B, C should be 1 and A is 0 to clock the middle ff. To get high at o/p is itself a reset state. Hence 110 is a toggle for reset. B=C=0 or B=0 and C=1 or vice versa are not possible. Hence the count is the answer i.e. mod-6.

Given Mod-6 counter is correct.

It is asynchronous counter with A as LSB (as clk is applied to A only).
Hence only up counting or down counting takes place.
Mod 6 is correct.
Hence only up counting or down counting takes place.
Mod 6 is correct.

Mod 3 is correct answer. Because MSB is always at right side in counters topic itself.

JK flip flop state is 2N:1.
N=3 flip flop,so mod=2N=2*3=6.
Ans:B.
N=3 flip flop,so mod=2N=2*3=6.
Ans:B.

I think its Better to Mention Which one is MSB and LSB in the question.

Answer should be MOD 7. Because if it starts from 000 (A,B and C respectively) it will go as below,
ABC
000
100
010
110
001
101
011
back to
000
Hence it is Mod 7.

I think the states will be like this,
000
101
011
100
101
110 (but the flipflops would reset at this state) so it is a mod 6 counter.
000
101
011
100
101
110 (but the flipflops would reset at this state) so it is a mod 6 counter.

Of course @Vijaya Venkat,
The answer follows like this I think.
000, 001, 010, 011 then counter resets. So the answer must be mod 3.
