    Answer : Option B

    Explanation :

    a) Since loga a = 1, so log10 10 = 1.

     

    (b) log (2 + 3) = log 5 and log (2 x 3) = log 6 = log 2 + log 3

     

          log (2 + 3)  log (2 x 3)(

     

    (c) Since loga 1 = 0, so log10 1 = 0.

     

    (d) log (1 + 2 + 3) = log 6 = log (1 x 2 x 3) = log 1 + log 2 + log 3.
