Answer
Correct Answer: $C$
Explanation
### Concept & Combined Ratios
To compare shares across multiple distinct ratios, they must first be synthesized into a single continuous combined ratio by finding a common multiple for the overlapping elements.
### Step-by-Step Solution
Given:
* $A:B = 3:4$
* $B:C = 5:6$
* $C:D = 7:5$
1. Combine the ratios using the standard multiplication method for four variables:
$A = 3 \times 5 \times 7 = 105$
$B = 4 \times 5 \times 7 = 140$
$C = 4 \times 6 \times 7 = 168$
$D = 4 \times 6 \times 5 = 120$
2. The combined ratio $A:B:C:D$ is $105 : 140 : 168 : 120$.
3. The maximum share corresponds to the largest number in the combined ratio.
4. Comparing the parts: $168$ is the largest value.
5. $168$ corresponds to $C$.
### Exam Strategy & Shortcut
You do not need to calculate the actual monetary shares. The question only asks *who* gets the maximum. Once you establish the unified ratio parts ($105, 140, 168, 120$), you immediately know $C$ has the largest proportion.
### Common Pitfall
Wasting valuable time calculating the exact monetary value for each person by dividing ₹ 1066 by the total ratio sum, when simply comparing the ratio units is sufficient.
### Final Answer
Therefore, the correct answer is **$C$**.
