Parts B and D have errors. In part B, the 'be' form of verb in continuous form 'being' already indicates the continuous tense of the sentence and the use of the verb 'recognising' in continuous/present participle form (V4) makes the part incorrect. Instead, the past participle form (V3) of the verb 'recognised' is to be used. In part D, the preposition 'by' is left out. The sentence is in passive voice and the subject has to be related to the verb through the preposition 'by'.
The correct sentence is: The wealthy urban single women are increasingly being recognised as an economic opportunity; they are wooed by banks, jewellery makers, consumer goods companies and travel agencies.
Hence, the correct answer is option (c).
Note:
A Preposition is a word placed before a noun or a pronoun or a noun equivalent (pronoun, adverb, gerund, infinitive, adverbial clause, or any clause that can be used as the object of the preposition) and shows a relationship in space or time or a logical relationship between two or more people, places, or things in a sentence.
Examples
I. The teacher scolded the child for being late.
II. We're going to a party.
· The words in bold are called prepositions because they normally take position before (pre) a noun/pronoun or a noun equivalent (pronoun, adverb, gerund, infinitive, adverbial clause, or any clause that can be used as the object of the preposition.
· The noun/pronoun which is used with a preposition is called its Object.
V1 -> Base form/simple form of verb, V2 -> Past form of verb (-ed form or irregular verb), V3 -> Past participle form of verb (-ed, -d, -t, -en, or -n), V4 -> Continuous form of verb / Present participle form of verb (-ing form), V5 -> Third person singular (V1+ -es or -s).
Active and Passive Voice: When the person doing the action is the subject, the sentence is said to be in active form/voice. When the subject is what the action is directed at, then the sentence is said to be in passive form/voice. For example: Active Voice: Rita and her friends performed a skit. Here 'Rita and her friends' (subject) perform the action. Passive Voice: A skit was performed by Rita and her friends. Here 'skit' is the subject (at which the action is directed).
