Expressing the reasons of choosing something Hi there! I'm writing a formal letter and I want to explain "the reasons of choosing something" but I wanted to be at the beginning of each paragraph. so are these sentences correct? 1- The main reason (why?) I chose to...... 2- With regard to the reason of opting for ..... 3- In regards why I narrowed my choice down to ..... are there other ways to express it ? Thank you
