Answer 2

A sentence is a group of words that is complete in itself.

There are four main types of sentences:

Simple or declarative sentence- It is used for information purpose.

Command or Imperative sentence- It is used to make requests or give orders, commands etc.

Question or Interrogative Sentence- It is used to ask questions and ends with a question mark(?).

Exclamatory Sentence- It is used to express emotions and ends with an exclamatory mark (!)

An affirmative sentence contains a positive form which can be transformed to negative form without changing the meaning just by changing a few words.

The correct answer is B)He was not sure that he would win the game.

Option B is correct as doubtful means not sure and the usage of not changes it to a negative sentence without changing the meaning.

The other options are wrong as not is not used,the meaning of the given sentence is changed  (lose) , and the sentence talks about the doubt of winning not losing.
