Devise the most efficient synthesis for the carboxylic acid below using a starting material and reagents from the tables. Give your route by specifying the number of the starting material followed by the letters of the reagents you would use beginning with the first step. The answer 44fh means treat t-butanol(4) with conc. HCl(f) then treat the product with KOH in alcohol(h).
