The correct Answer is:
A
`|{:(+rArr+,-rArrxx),(xxrArr+,+rArr-):}|`
Option (1)
`5xx8-5+5+1=12`
`rArr 5+8xx5div5-1=12`
`rArr 5+8xx1-1=12`
`rArr5+8xx1-1=12`
`rArr 5+8-1=12`
Option (2)
`55-2+10div1xx5=16`
`rArr 55xx2div10-1+5=16`
`rArr (55xx2)/(10)-1+5=16`
`rArr 11-1+5 ne16`
Option (3)
`38 div 10-5+7xx8=25`
`rArr 38-10xx5div7+8=25`
`rArr 38-(10xx5)/(7)+8=25`
`rArr 38-(50)/(7)+8 ne 25`
Option (4)
`10-12+2div30xx1=10`
`rArr 10xx12div2-30+1=10`
`rArr 10 xx 6-30+1=10`
`rArr 60-30+1 ne 10`
