To calculate the TF-IDF value, we need to follow these steps:

1. Calculate Term Frequency (TF): This is the number of times a word appears in a document divided by the total number of words in the document. In this case, "Difficult Task" appears 8 times in the document. However, we don't know the total number of words in the document, so we can't calculate the exact TF value.

2. Calculate Inverse Document Frequency (IDF): This is the log of the number of documents divided by the number of documents that contain the word. In this case, there are 1000 documents and 50 documents contain the term "Difficult Task". So, IDF = log(1000/50) = 1.3 (approximately).

3. Multiply TF and IDF: The TF-IDF value is the multiplication of TF and IDF. Since we don't have the exact TF value, we can't calculate the exact TF-IDF value.

Without the total number of words in the document, we can't calculate the exact TF-IDF value. However, we can say that the TF-IDF value is not zero because the term "Difficult Task" appears in the document. Also, it's not 81.1 because this value is too high for a TF-IDF value. So, the answer is not in the given choices.
