The color transition pH range of the indicators are given below:

Methyl orange : 3\cdot 1-4\cdot 4

Phenolphthalein : 8\cdot 3-10

Now, titration of a strong acid and weak base can be indicated by methyl orange as the pH at equivalence point will lie in the acidic range .

Titration of a weak acid wilt a strong base can be indicated by Phenolphthalein as the pH at equivalence point will lie in the basic range .

Hence, Statement I is true while statement II  is false .

Therefore , the correct answer is option (4)
