Given List<int> nums = new List<int> {7, 2, 9, 4, 6};
Which code snippet correctly finds the first number greater than 5 and removes it from the list?

Anums.Remove(nums.Find(x => x < 5));

Bnums.RemoveAt(nums.FindIndex(x => x > 5));

Cnums.Remove(nums.FindIndex(x => x > 5));

Dint val = nums.Find(x => x > 5); nums.Remove(val);

Step-by-Step Solution

Solution:

Step 1: Find first number > 5
nums.Find(x => x > 5) returns the first matching value.
Step 2: Remove that value
nums.Remove(val) removes the first occurrence of that value.
Step 3: Check other options
nums.RemoveAt(nums.FindIndex(x => x > 5)); removes by index correctly but is less clear; nums.Remove(nums.FindIndex(x => x > 5)); passes index to Remove which expects a value; nums.Remove(nums.Find(x => x < 5)); removes a number < 5 which is incorrect.
Final Answer:
int val = nums.Find(x => x > 5); nums.Remove(val); -> Option D
Quick Check:
Find returns value, Remove removes by value [OK]

Quick Trick: Find returns value; Remove removes by value [OK]
