A. CORRECT. Comparison between “the males” and “the females” is correctly established. Use of present participle “spending” makes it clear in what way the males are more interested in collecting food. Use of present participle “searching” correctly establishes its bearing on “spending” - this construction makes it clear how the males spend time in deep waters.
B. The three items “ in collecting”, “ in spending” and “ in searching” are wrongly made parallel. This construction indicates that the males are interested in all these three items parallelly and the bearings between these items are lost.
C. Comparison is ambiguous: It is not clear what is meant, whether
1. the males are more interested in collecting food than in females
or whether
2. the males are more interested in collecting food than the females are
The three verbs “are interested”, “spend” and “search” are wrongly made parallel. This construction indicates that the males execute these three activities parallelly and the bearings between these items are lost.
D. Comparison is ambiguous: It is not clear what is meant, whether
1. the males are more interested in collecting food than in females
or whether
2. the males are more interested in collecting food than the females are.
The two present participles “spending” and “searching” are wrongly made parallel. This construction does not make it clear how the males spend time in deep water, i.e. it is not clear that the males spend time in deep waters searching for food - the bearing between “spending” and “searching” is thereby lost.
E. The relative clause “who spend…” wrongly refers to “the females”, conveying the wrong meaning. The intended meaning is that the males spend time.
