Verbal Ability - Spotting Errors - Discussion

@ Dhairya Lakhera - Your point is valid and the correct answer should be option 'C' . In option B the Noun clause is replaced by a Noun phrase and it is perfectly fine.

Example:

Do you know English - correct
Do you know how to make out - correct
DO you know to count beans - correct

@ Kartikeya - Your point is logical except, for referring a general object we should use 'a'

The correct sentance should be:

1- Do you know how to play a guitar?

Or

2- Do you know to play a guitar?

Hope this helps.

A GUITAR!

To play/ how to play A GUITAR.

Difference between written and spoken language. I think the correct answer should be C.

The above explanations given Dhairya and Akash make complete sense.

It can also be 'Do you know to play guitar?'.

I think C has not a punctually right because there is a question mark.

I totally agree with @Akash and I think option C must be the correct answer here, as we are referring to a common/general object therefore must use 'a guitar' instead of 'the guitar'.

Hence the answer: Do you know to play a guitar?

Absolutely. C must be the correct option. We cannot play THE Guitar. We play Guitar. It is simply because we cannot know THE English, but we can know English. And I don't know what's the problem with PLAY (Option B).

@ Avinash.

Considering the clause 'How to play. ' can simplify this. It has been promoted to the main clause from subordinate clause so the 'how', with a gut feeling, will better suit in that clause.

'The' should not be used and correct answer should be C.

First, Guitar is Noun so it's the first error.

Next, it will be how to play.
