In a certain code language, 'CACTUS' is written as 'ACTCSU' and 'DESERT' is written as 'EDESTR'. How will 'SAFARI' be written in that language?

Let's analyze how the letters are permuted in pairs:For CACTUS $\to$ ACTCSU:Pair 1: C A $\to$ A C (Swapped)Pair 2: C T $\to$ T C (Swapped)Pair 3: U S $\to$ S U (Swapped)Let's check DESERT $\to$ EDESTR:Pair 1: D E $\to$ E D (Swapped)Pair 2: S E $\to$ E S (Swapped)Pair 3: R T $\to$ T R (Swapped)The logic is simply swapping adjacent pairs of letters. Let's apply this to SAFARI:Pair 1: S A $\to$ A SPair 2: F A $\to$ A FPair 3: R I $\to$ I RCombining them gives ASAFIR.
