JAVA CERTIFICATION QUESTION: Sorting lists by multiple criteria

Given:

and this code fragment:

𝐖𝐡𝐢𝐜𝐡 𝐜𝐨𝐝𝐞 𝐬𝐨𝐫𝐭𝐬 𝐚𝐧𝐢𝐦𝐚𝐥𝐬 𝐢𝐧 𝐭𝐡𝐞 𝐨𝐫𝐝𝐞𝐫: 𝐖𝐨𝐫𝐦, 𝐅𝐥𝐲, 𝐃𝐫𝐚𝐠𝐨𝐧𝐟𝐥𝐲, 𝐒𝐩𝐢𝐝𝐞𝐫?

𝐀. 

list.stream().sorted(Comparator.comparing(a -> a.getNumOfLegs()).thenComparing(a -> a.getNumOfWings())).collect(Collectors.toList());

𝐁. 

list.stream().sorted(Comparator.comparing(a -> a.getNumOfWings()).thenComparing(a -> a.getNumOfLegs())).collect(Collectors.toList());

𝐂. 

list.stream().sorted(Comparator.comparing(a -> a.getNumOfLegs())).sorted(Comparator.comparing(a -> a.getNumOfWings())).collect(Collectors.toList());

𝐃.

list.sort((la, ra) -> {

ˑif (la.getNumOfLegs() == ra.getNumOfLegs()) {

ˑˑreturn Integer.compare(la.getNumOfWings(),

ˑˑˑ ra.getNumOfWings());

ˑ} else {

ˑˑreturn Integer.compare(la.getNumOfLegs(),

ˑˑˑra.getNumOfLegs());|

ˑ}

});
