Correct option is C
·
Correct option: (c) interest rates four times since last January.
·
Explanation: The sentence refers to an action that began in the past and continues to the present, thus the correct usage is present perfect with “since”.
·
Grammatical rule used:
·
Present Perfect Tense with “since” is used to describe an action that started at a specific point in the past and continues.
· Structure: has/have + past participle + since + time point.
·
Hindi rule: "Since" के साथ जब कोई कार्य भूतकाल में शुरू हुआ और वर्तमान तक प्रभावी है, तो Present Perfect Tense का प्रयोग किया जाता है।
·
Example: They have visited us several times since January.
·
Meanings of other options:
·
(a) Grammatically incorrect; "for times" should be "four times".
·
Hindi: व्याकरणिक त्रुटि है।
·
(b) Incorrect because it misuses “from” with Present Perfect.
·
Hindi: Present Perfect Tense के साथ "since" का प्रयोग होता है।
·
(d) Incorrect article usage and wrong verb form.
·
Hindi: "time" की जगह "times" और "the" अनावश्यक है।
