Answer 1

Hint:
 A noun is a content word that can be used to refer to a person, place, thing, quality, or action. The noun is the word class that can serve as the subject or object of a verb, the object of a preposition, or in apposition.

Complete answer:
In the given question, we have to find out which of the given options contain a noun to fit in the blank as there is already an auxiliary verb and a main verb in the sentence.
Let us thus analyze the options given to us in this question-
Option (A), 'to tell', refers to a preposition ‘to’ which indicates purpose, and a verb ‘tell.’
Therefore, option (A) is incorrect.
Option (B), ‘telling', is a noun which is defined as ‘disclosing information or giving evidence about another.’ Therefore, option (B) is correct as ‘telling’ is a noun.
Option (C), ‘having told', refers to the past perfect continuous tense form of the verb ‘tell.’ Therefore, option (C) is incorrect.
Option (D), ‘having been told', is incorrect as it does not include any noun whatsoever.
Hence option (B) is correct. 

Note:
In this question, it will be helpful for the student to recall the concept of tense. Tense is a grammatical category of verbs used to express distinctions of time. There are three tenses- past, present, and future.
