Answer

Exam answer

Odd one out: TELOPHASE. Category of the others: PHASES OF THE MENSTRUAL CYCLE.

Explanation

Menstrual, follicular and luteal are three of the four phases of the MENSTRUAL CYCLE (the fourth being the ovulatory phase).

TELOPHASE is the last stage of MITOSIS — cell division, an entirely different topic.

THE TRAP is the word PHASE, which appears in all four terms and invites you to think they belong together. The shared word is deliberately misleading: what matters is what the phase is a phase OF.

The menstrual cycle in order, worth knowing as a set: MENSTRUAL (days 1-5, lining shed) → FOLLICULAR (6-13, follicle grows, lining rebuilt) → OVULATORY (about day 14) → LUTEAL (15-28, corpus luteum secretes progesterone).
