The given set of inequality is expressed as
- 11 > 1 + a
The first step is to subtract 1 from both sides of the inequality. It becomes
- 11 - 1 > 1 - 1 + a
- 12 > a
The meaning is '- 12 is greater than a'
This also mean that 'a is lesser than - 12'
the expression would be
a < - 12
Thus, the correct option is A
