Step by step answer
A noun clause is a group of words that function as a noun and contains a subject and a predicate of its own and does the work of a noun. It is a dependent clause that depends on the principal clause.
I don't know where I should catch the train from
In this sentence, the underlined part is the noun clause because here ‘I’ work as a subject and catch the train from work as a predicate part. So it is a group of words that function as a noun and contains a subject and predicate of its own.
We have to change the underline part into a noun phrase.
For changing noun clauses into noun phrases we have to remove the subject and change the verb into infinitive phrases or gerund phrases.
In all the options the subject is not present then we have to look at the verb part.
Option A : I don't know where to go
If we choose option A then it is a noun phrase but this does not completely change the meaning. So it is not the correct option.
Option B: I don't know where to catch the train from
It is a noun phrase. We remove the subject I and change the verb should catch into to catch( infinite phrase). So it is the correct option.
Option C: I don't know how to catch the train.
It is also a noun phrase but changes into how so the meaning changes. So it is not the correct answer.
Option D: It is not the correct option because we find the answer in option(B).

Note:
By changing noun clauses into noun phrases we can make complex sentences into simple sentences. In the above sentence where I should catch the train depending on the principal clause (I don't know) so it is a complex sentence and we change it into I don't know where to catch a train from that is a simple sentence.
