I can't call him now because I have lost his telephone no. (Option A)

• The present perfect tense refers to an action or situation that occurred at an undetermined period in the past (e.g., we have previously discussed) or that began in the past and proceeded until the present moment (e.g., he has grown impatient over the last hour).
• This tense is produced by the conjunction have/has plus the past participle.
• The present perfect is generated by combining the present tense of the verb have and a verb's past participle.
• As a result, the tense in the provided phrase will be 'have lost.'
