b. When had television invented?
c. When television had been invented?
d. When was television invented?

Answer 1

Hint: Look for pointers suggesting which words and phrases to use. The words given in the bracket suggest that the time period of the invention of television is being asked about.

Complete answer:
 The question asks us to frame an appropriate question. This means that we need to construct an interrogative question. An interrogative sentence is a sentence that attempts to retrieve information and ends with a question mark. The sentence has to be constructed in a certain way for it to be considered grammatically correct. The construction is as follows: ‘wh’ word + verb + object.

If the interrogative sentence is arranged in any other way, it is considered grammatically incorrect. The tense of the given sentence needs to match the situation being talked about. The object being asked about is a television and its invention. The invention of television has already happened, so we need a simple past tense.

Now, we know exactly which type of sentence we need. Let’s look at the given options-
a. When television was invented? - This particular option does not follow the above construction, and so it is grammatically incorrect. This is not the required answer. So, this is an incorrect option.
b. When had television invented? - This particular option does not follow the above construction, and so it is grammatically incorrect. This is not the required answer. So, this is an incorrect option.
c. When television had been invented? - This option also does not follow the above construction, and so it is grammatically incorrect. This is not the required answer. So, this is an incorrect option.
d. When was television invented? This option follows the above-given format and it is grammatically correct. This is the required answer. So, this is the correct option.

Note:
Read the given sentence carefully, and try to understand the meaning of the sentence. Then, read the given options. Then, choose the option that you think sounds the most correct and fits perfectly into the given blank.
