Each question has four words given in bold which may or may not be arranged in the correct order and need an interchange between them. Choose the interchange required to make the sentence grammatically and contextually correct.

Preventive (A) measures must be taken to make sure that current (B) investments (C) do not fail like the future(D) ones.

Correct option is B

Though the sentence has no grammatical mistakes in it, it lacks logical sense. Interchange between ‘ future’ and ‘ current’ would provide the required logic as we can anticipate success from the ‘future’ investments. Other rearrangements are also failed to give coherent order to these highlighted words.
Thus, the sentence will be,
Preventive measures must be taken to make sure that future investments do not fail like the current ones.
