Solution

## The correct option is A =25.26(27−1) For each historical monument, there are two possibilities either he visits or does not visit. Similarly for gardens. Total number of ways =25.26(27−1) We have subtracted one from shopping mall, as that will include one case where he does not visit any mall.
