Correct option is A
Option (a) contains an error.
Detailed explanation: The fixed prepositional collocation is “in the absence of”, not “in the absence from.” Therefore, the sentence should read: “In the absence of any evidence, the court had to acquit him.” “Absence of + noun” expresses non-availability/lack (किसी चीज़ की कमी/अनुपस्थिति).
Grammatical rule used: Certain nouns take fixed prepositions (collocations), e.g., reason for, need for, demand for, lack of, increase in, interest in, absent from (but in the absence of).
Example: In the absence of clear rules, people made their own arrangements.
Information booster / exceptions:
· Absent from is correct with the adjective “absent”: He was absent from class.
· But with the noun “absence,” use of: The absence of evidence weakened the case.
