No need of calculations..

The denominator is NEGATIVE, while the numerator is positive, so our answer is NEGATIVE.
Only A and B left.
B is -1......Numerator and denominator are clearly not equal in absolute value.. Eliminate

Hit A

\(\frac{\frac{2}{3} + \frac{3}{4}}{\frac{2}{3} - \frac{3}{4}}≈\frac{0.666 + 0.75}{0.666 - 0.75}\)

\(≈\frac{some.value.greater.than.1}{some.small.negative.value}\)

= some negative value that is NOT -1
