下列Python代码的while循环实现中，与给定for循环功能完全等价的是？

给定for循环代码如下：

res = 0
nums = [2,4,6,8,10]
for num in nums:
    res += num
print(res)

res = 0
nums = [2,4,6,8,10]
index = 0
while index < len(nums):
    res += nums[index]
    index += 1
print(res)

res = 0
nums = [2,4,6,8,10]
index = 0
while index <= len(nums):
    res += nums[index]
    index += 1
print(res)

res = 0
nums = [2,4,6,8,10]
index = 1
while index < len(nums):
    res += nums[index]
    index += 1
print(res)

res = 0
nums = [2,4,6,8,10]
index = 0
while index < len(nums):
    index += 1
    res += nums[index]
print(res)
