It means that and is use for the multiplication purpose.
1 1 = 1 means on to checks.
1 0 = 0 off.
0 1 = 0 off.
0 1 = 0 off.
1 1 = 1 means on to checks.
1 0 = 0 off.
0 1 = 0 off.
0 1 = 0 off.

1st option is WRONG because & operator never works on single bit ,it require minimum 2 bit like ( 1 & 1 = 1 or 1 & 0 = 0), so no hope for 1.
2nd option is WRONG because 1 & 1 = 1 i.e ON. when bits are already ON then it makes no sense.
3rd is CORRECT because 1 & 0 = 0 i.e OFF. it makes sense here. Any one of the bit is OFF then Then results comes OFF.
4th is also CORRECT. when u have a bit ,try to AND it with 1 and if you get result 1 i.e ON then Prev bit was 1 i.e 1
and if you get result 0 (OFF) then but obvious Prev bit was 0 that's why option 5 is also CORRECT

3. If bit is ON means bit=1 by ending this bit with 0 we can OFF this bit i.e 1&0=0.
4 and 5. We can check a bit is ON by ending bit with 1 i.e
If bit&1=1 (bit is ON) else bit is OFF.
So Points 3,4 and 5 are correct.
