Answer / Shikha
'ToDictionary()' is a LINQ extension method that converts an IEnumerable to a Dictionary. It takes two optional arguments: a key selector and a comparer for the keys. 'IEnumerable<KeyValuePair<TKey, TElement>>' is the returned type. On the other hand, 'IEnumerable<T>' is the base type returned by most LINQ methods, representing an enumerable collection of elements.
