Considerando log 2 = \( \dfrac t 2 \), assinale a alternativa que apresenta o valor de \( x \), sabendo que:

\( x \) = log\( \biggl ( \dfrac 2 3 \biggr ) \) + log\( \biggl ( \dfrac 3 4 \biggr ) \) + log\( \biggl ( \dfrac 4 5 \biggr ) \) + \( \cdots \) + log\( \biggl ( \dfrac 8 9 \biggr ) \) + log\( \biggl ( \dfrac 9 {10} \biggr ) \)
