OptomCAS Application Q's for MCPHS

"Please explain any F's, D's, W's, or leaves of absences that appear on your transcript(s)." Hi, can anyone help me find out how to answer this? I want to ensure I use the correct wording: I only have a D from Organic Chem I & a W in Statistics just because I didn't understand. I later took it and passed the following semester. Any comment is much appreciated!
