Couples who are passionately in love most frequently communicate intimacy by means of
a. prolonged eye-gazing.
b. raising just the inner parts of the eyebrows.
c. averted glances.
d. contraction of the pupils. winking.

The correct answer is a. prolonged eye-gazing.

Explanation:

Research has shown that oxytocin is released during prolonged eye gazing. Oxytocin is commonly associated with love, trust, and empathy. It counters the effect of the stress hormone, cortisol, making people feel tranquil. When couples are in love, they tend to gaze at each other for long periods of time during which oxytocin is released, making them feel even better and happier.
