Since there is major confusion between Choices A and C, I will only focus on A, C in my solution.
Original Sentence - Choice A
Asset allocators create portfolios{,...,} with the intention to turn in good results.
Meaning - In this choice, the modifier "with the intention to..." modifies the action of asset allocators. It provides the reason why asset allocators created certain portfolios. Notice that the portion of the sentence within commas - often in the form of mutual funds, describes the "portfolios".
Errors - This choice has idiom error. The correct idiom is "with the intention of turning".
Choice C
Asset allocators create portfolios {,...,} intended to {turn in...}.
Meaning Now in this choice, the modifier has been changed to "intended to..." and it appropriately modifies portfolios. The sentence conveys the intended meaning of the sentence. Asset allocators created certain portfolios. These portfolios were intended to turn in good results. Thus in essence, the intention of asset allocators to turn in good results is met.
Please note that if Choice A is worded with correct idiom, it will be correct:
Asset allocators create portfolios with the intention of turning in good results.

"Both firms agreed to buy some of the securities
with the intention of reselling them or making a secondary market for them"
In this sentence, the modifier "with the intention of making..." modifies the action taken by the firms. It provides the reason behind the action.
If this sentence is to be re-written in the form of Choice C, then we will need to reword it as follows:
"Both firms agreed to buy some of the securities
intended to be resold or to create a secondary market for them.
