Which of the following statements is accurate?
can someone me with this question?

The option B is correct.

#in my opinion#

Explanation:

As we know that the wavelength is the length of one wave and is measured in case of longitudinal wave as the distance between two consecutive compressions or rarefactions and in case of transverse wave as distance between two consecutive crests or troughs THUS in both cases we measure the distance in the direction of the wave (parallel to the wave).

in cartography, a contour line (often just called a "contour") joins points of equal elevation (height) above a given level, such as mean sea level. a contour map is a map illustrated with contour lines, for example a topographic map, which thus shows valleys and hills, and the steepness or gentleness of slopes.

explanation:

both adhesion and cohesion are attractions.

they are different in that adhesion is the force of attraction between the molecules of two different substances, whereas cohesion is the force of attraction between molecules of the same substance.

possible examples include capillary action, in which the adhesion between water and glass causes the water to rise in a narrow tube against the force of gravity.

because of hydrogen bonding, water is extremely cohesive.

this causes molecules on the surface of water to be drawn inward, which is why drops of water form beads on smooth surfaces.
