In a certain code language, CREATIVE is written as BDSBFUJS. How is TRIANGLE written in that code?

• (A) BHSSFKHM
• (B) BHSSMHHF

 The letters in the first half and second half of the word are written n the reverse order and then in the group of letters so obtained, the first, third, fifth and seventh letters are each moved one step forward while the second, fourth, sixth and eighth letters are each moved one step backward to get the code. Thus, we have : TRIANGLE => TRIA/NGLE => AIRT/ELGN => BHSSFKHM.
