The hardness in your breast
A= 3 (we can taste 5 main sensations)
B=2 (You can actually distinguish up to 1 trillion scents, you just have to train your nose to remember the difference, that's why it says hundreds because that's about average)
C=1 (Pressure, temperature, pain, texture, and vibration are the main senses of touch, however, just because there are 5 major senses of touch doesn't make this match to A because taste has 5 types of taste while this specifies tactile senses)
D=4 (preconception refers to bodily movement, position, and sensation)
Hope this helps!
